Linux Based Virtualization (HPE ProLiant Gen9 Server) Using Docker + LXC Wed, 04 Jul 2018 07:10:45 +0000 Virtualization tech-n9ne 132846@/discussions

I have a HPE ProLiant Gen9 Server (wich would be the core piece of my Information System) and want to run multiple applications on it like: ECM, VoIP, Owncloud, pfsense, Zentyal and maybe others for an organization of like 100 to 1000 users.

I have choosed to use Canonical Ubuntu for Core OS (supported for Linux by HPE) as I don't want no Microsoft Software. So I I'm planning to install Docker on that Ubuntu Server core OS to run my several apps as LXCs via Docker.

Then I have multiple questions:

1- Is it necessary for me to include proxmox in the stack? If yes what would be the role (importance) of proxmox ?
2- I want to use pfsense as firewall/router and Zentyal for other services such as domain controller and so on. Is it possible to use those two in the same environment without conflicts?
3- Installing pfsense and/or Zentyal phisically on the Ubuntu Server core OS or installing them in LXCs (via Docker)? What would be better? Or Should I install Zentyal physically on the core OS and pfsense in LXC or vice-versa? What would be better?

Thanks in advances for your precious answers icon_thumright.gif]]>

Resources for Stanly CC ICM course Wed, 16 May 2018 16:03:49 +0000 Virtualization cicumag 132336@/discussions
I hope this is allowed to be asked but i know many of you have gone through the Stanly CC course for ICM. I am in the class starting at the end of this month. I wanted to ask, is buying the book is mandatory? I know it's not really expensive but i have access to books 24x7 and safari and if the book is there i can simply use that resource.

My real question is, what is the book they use and do i need to purchase it through the bookstore? Thanks for any insight.]]>
Portquery show filtered but no firewall block Mon, 14 May 2018 17:53:24 +0000 Virtualization shanparames 132311@/discussions
There are multiple VLAN's trunked to an ESXi host. In one VLAN, all the Windows servers hosted in that ESXi cluster are getting connected through RDP.

We are building new VM's in another VLAN newly created by Network team.We deployed VM's and assigned ip addresses to them .But we are not able to take RDP from outside the VLAN.All the VM's inside the particular VLAN are able to ping the default gateway and the external ip addresses .Port 3389 is found open in all the Vm's in that VLAN (since all are deployed through one common image.) I can able to take the RDP from the VM's inside that VLAN to one and another in the same VLAN which confirmed that too.

I did the port query from the citrix jump server to the destination VM in that VLAN for the port 3389 . Got the result as filtered which is clear enough that port 3389 is blocked.
So I raised the firewall request for the standard ports to be opened as per our enterprise firewall rules to the particular subnet ( VLAN).The firewall person executed the request , in spite of that I am unable to connect via the RDP and still the port query showing the port 3389 as filtered.
During the troubleshooting done by the firewall person , he is saying there is no firewall between the source and the destination ( I provided the tracert output to him )and he is not able to see any traffic flowing between the endpoints in realtime when I executed the continuous ping between the endpoints.

He is advising to check the issue with the Datacenter networking persons.Anybody encountered like this issue , if then please advise how and where to start the investigation .....]]>
Question on ESXi trunking and frames details Tue, 24 Apr 2018 15:37:17 +0000 Virtualization shanparames 132094@/discussions
I have posted the question from Vmware ESXi standpoint but it is more of networking stuff . That is why I posted here .Anybody please answer with the details in Cisco way
Brief explanation of Above mentioned Scenario:

There are three VMs connected to vSwitch.
VM1 Mac Adress is AA
VM2 Mac Address is BB
VM3 Mac Address is CC
vmnic0 is uplink connected to Physical Switch Port ( Let’s say 0/1).
This Uplink Mac Address is XX.

The question here is

How Physical Switch will be processing VMs Packets coming from vSwitch and goes on Wire.

  1. Physical Switch will be masking all VMs MAC address with Uplink Mac Address(XX) ( similar to NAT implementation)
  2. Virtual Switch will be masking all outgoing VMs MAC address with Uplink Mac Address
  3. Physical Switch Will be learning VMs MAC address and updating MAC table with only VMs MAC address.
  4. Physical Switch will having both VM MAC address and Uplink Mac Address in its MAC table

Any advice is highly appreciated!]]>

She gets on the phone with Pearson technical support and the technical support conclusion is that the lab environment has backspace disabled on purpose! icon_eek.gif Told them that that can't be right and to generate an incident report because there's no way I'm doing a deploy exam without a working backspace key.

She said she'll generate a report and I'll get a copy. Guess I'll figure out the next steps after getting the report.]]>

issues with Advanced System Settings that are causing errors Tue, 18 Jul 2017 11:26:35 +0000 Virtualization lostbackups 128116@/discussions I did vCenter first of course and now I am starting on our esxi hosts. After first esxi host upgrade to 6.5, I got an alert saying "system logs are stored on non-persistent storage". So I found the setting Advanced System Settings of the host and changed that parameter to a datastore. But then when I attempted to save the changes it alerts me that there are other parameters that are unacceptable. I attempted to change these parameters as well but one of them I am unable to change to what I need to be and the other one I have no idea what it should be.
These are the settings in question:
  • Net.NetPktSlabFreePercentThreshold - currently set to 2 but it says it has to be between 10 - 50. I really don't know what it should be.
  • VSAN-iSCSI.ctlWorkerThreads - currently set to 4294967295 but I want to set it to -1 but the field is not allowing me to enter the negative sign! (Number of worker threads. -1 means auto-calculate based on CPU count)

HOL for VCAP? Sat, 30 Sep 2017 07:25:39 +0000 Virtualization GBAKER2204 129346@/discussions VMware Workstation Pro less of a hassle than VirtualBox? Wed, 08 Nov 2017 10:29:24 +0000 Virtualization yoba222 129914@/discussions
VirtualBox is fantastic for me when it's up to date and configured correctly. My use case is running 2-10 simultaneous virtual sandboxes that I use for labbing.

The problem is whenever VirtualBox puts out an update I have to deal with re-installing guest additions, which occasionally break the guest OS installation in some way. Guest additions are a big deal to me as they usually correct screen resolution scaling issues and allow sharing of the clipboard between the host OS and the guests. The VMware equivalent to Guest Additions is VMware Tools.

2017 is not yet complete and this year alone there have been 9 VirtualBox updates. So about once a month I cross my fingers in applying a patch that I hopefully did not just bork my guest OSes in some way. The vast majority of the time things are fine, but not always.

Can't argue with its price: VirtualBox is free. VMware Workstation Player is free too, but what an utterly useless product: only one guest OS can be run at a time. VMware Workstation Pro is far from free at $250 for a license.

So does VMware Workstation Pro also have the same hassle of near-monthly updates and having to constantly update VMware Tools on the guest OS? I'd seriously consider paying $250 for a license if I had peace of mind without having the hassle of constant updates that may ruin the extended functionalities.]]>

Mon, 30 Oct 2017 11:10:07 +0000 Virtualization shtooo 129801@/discussions Best options for multiple vendor study lab? White box or Nucs Sat, 30 Sep 2017 12:13:01 +0000 Virtualization GBAKER2204 129352@/discussions
I am currently in what I expect to be in a unique position where I can invest in a lab (inheritance - approx £1800 budget+ EvalExperience), where previously cost has prevented doing so (married with 2 children and a mortgage, normally with other more family orientated costs to save for pay for). I don't want to waste the opportunity to build a lab that may be useable for a good number of years going forward, without massive energy costs or large amounts of space being taken up. Whilst a cheap second hand server may be an option I am concerned about the energy costs and noise associated.

I currently work as an infrastructure operations engineer, so work with a good range of technologies (VSphere/Citrix/Netapp/Cisco/various Linux distributions/MS Servers/System Center). Currently VCP-DCV certified, looking at VCAP or other VCPs, have taken the CCA-V course so looking at building out a lab for that too (do Citrix do cheap/reasonably priced labs?), and need to upgrade my MCITP 2008 to 2012/2016 before the upgrade paths disappear.

After a couple of busy years where life got in the way of study I now want to move forward and get the above started.

Any thoughts or suggestions greatly appreciated.]]>

My background is,

I work for a fortune 200 company and have been heavily involved in about twenty five enterprise class VMware designs/deployments over the last four years. Basically me and another employee have designed and implemented the compute, storage, DR, and decent parts of the network for these deployments. Granted most of them have been very similar, but we have refreshed these environments all at least once and the migrations/refreshes have presented some unique challenges. I've become proficient with Netapps, HP Blades, very strong with VMware, decent knowledge of Cisco Nexus for a server guy, good knowledge of SRM. Only one deployment has featured fibre channel, the rest have been NFS, zero ISCSI. Basically my role the last four years or so has almost been an internal consultant.

So what I am wondering is, how well does my background fit up to what you guys would expect the successful VCDX candidate to be? I'd love to hear from a VCDX or anyone who has attempted the defense, but I value many TE members opinions. I am interested in any and all feedback, tips, etc.

My general game plan is 12-18 months, VCP5, VCAP-DCD5, VCAP-DCA5, design, defense. I am planning to travel to VMware pex 2015 for VCDX bootcamp if it's open to the public. I am estimating ~1k-1500 hour investment. I am single, no kids, workload at work has really dropped off, so I am hoping for 21 hours a week.

Why do I want to do this? I want the opportunity to work on the largest/toughest projects in the world, wherever I want in the world, and I want the financial rewards. I want to be able to reach a point in life where I can afford to give back to worthy causes of my choosing.

Thanks in advance guys.]]>
