Using PowerCLI to create Virtual Machine Port Groups

Networking, VMware, , , ,

So basically I had a host failure where all of the configure was lost, if I was more savvy with Powershell/PowerCLI, I would have been able to rebuild it all via scripts, but that clones the settings from a working host.

But nevermind that is for a different day of learning.

So I configured the host to the point of Networking, so the vSwitches had the correct NICs, but I needed to do all the port groups, which in the GUI if you have a few to do is time consuming.

So in PowereCLI, pull all of your information, port-group names and VLAN IDs.

Get-Vmhost -name <FQDN of host> | Get-VirtualSwitch -name  | Get-VirtualPortGroup

To create a port-group

Get-Vmhost -name <FQDN of host> | Get-VirtualSwitch -Name  | New-VirtualPortgroup -Name "Name of PG" -VlanID

Obviously this is a very short crude method of achieving what I need, but here you can see the basic building blocks needed to create Port Group in PowerCLI.

Looking back at a VMware VDI Deployment

General, VMware, , , , , , , , , , , , , ,

My good friend Nathan Bryne wrote a good post about “Do I really need to do a Desktop Assessment?“, which got me thinking.

I worked at a college for around 3 years where we had a 1000 seat VMware View VDI deployment. I started working there just after the college had decided to go all-in on VDI and purchased the equipment, as most of their student machines were getting to 5 years old, and in some areas 7 years old.

The highlights of this were;

HP-AMS Driver causes ESXi memory leak

VMware, , , , , , , , , ,

So basically I had a customer hit by a known HP-AMS driver issue (KB2085618), the symptons were as follows;

  • Unable to vMotion a VM to another host, gives “operation timed out error”

2014-11-10_10-36-15

  • If power off VM, vMotion a machine to another host, and then power on, you get the following error “Could not start VMX: msg.vmk.status.VMK_NO_MEMORY”

ESXi memory leak

This issue is caused by a memory leak in the driver which fills the SWAP memory of the ESXi host, making it unable to response to any requests at all,

For example, trying to enable SSH;

Veeam upgrade to v8 – Enterprise Manager fails with Access Control List error

Veeam v8 is here – New Features and Upgrade Process

General, VMware, , , ,

So Veeam’s High Availability Suite is here!!!! Basically v8.

So in this post we are looking at Features and the upgrade of the program, and using the program when updated.

New Features
Backup and Replication

My favourite feature which doesn’t seem to be in the documentation online, is Snapshot Hunter, where Veeam actively looks for and removes any snapshots which havent deleted properly, i.e where vCenter said snapshot removed, and it hasn’t!!!

High-Speed Recovery

Active Directory: Granular-level recovery and low recovery time objectives (RTOs) Continue reading Veeam v8 is here – New Features and Upgrade Process →
