Need Script Made to save time

randvegeta

Hello all.

We use XEN for our VPS and there is a bug in it / our provisioning system.

Basically, when a node gets full, the provisioning system continues to attempt to build the VPS on the node. It fails because it's full, but the new VM actually exist on the node anyway, just does not start and doesnt have any virtual disks.

So our provisioning system was endlessly trying to create new VMs on a node that is now full, and there are several thousand (halted) VMs on the node.

There are so many VMs that XenCenter no longer works. I do not have a list of the VM UUIDs, but they can be found using the xe vm-list name-label= command.

I can basically only see/list 56 VMs at a time.

Can anyone write some sort of bash script that finds all the UUIDs (based on the server name) and then deletes the VMs?

What provisioning system are you using ? Are you using Xen or Xenserver. We ended on PXE provisioning and that worked fine. Everything else was too buggy for Xenserver. Alternative is CloudStack or OpenStack

NOC-PS and XenServer

drserver

Yes, we had same issues with that combo.

I manually deleted some 1,500 VMs and was finally able to access the server via XenCenter.

Now attempting to delete all of the bad VMs, but it's hanging like crazy. Will see how it goes after 2 hours.

We ended up with Virtualizor. Good luck

I'm also using Virtualizor, but still have many that were originally setup with NOC-PS.

BTW, are you using Virtualizor with XenServer? Or KVM?

drserver

With booth, We do Xen, XenServer and KVM

Whoops, ignore this.

I can help you with a bash script but before that, you should show me the output of xe vm-list command.

Already sorted this 2 weeks ago I'm afraid.
