XCP-NG -- VMs shut down / fail to boot after warm migration
-
Good evening friends,
I'm migrating a handful of VMs over from Xencenter 7.6 to XCP-NG Center 20.04. I'm running into a spot of trouble with a handful of VMs - they migrate over fine, but will not automatically start. Moreover, when I try to manually start them, they immediately shut down after hitting the "Boot device: Hard Disk - success" screen:
A couple of troubleshooting thoughts:
1.) The majority of VMs that appear to have this issue appear to be running Ubuntu 14.04. When booting in, if I manually access the GRUB menu and choose a Linux kernel that is older than 3.13.0-39, it does boot without issue. However choosing anything newer than that fails to boot.
2.) I've tried a handful of Ubuntu 16 and 18 VMs, and those appear to boot without issue. However one Ubuntu 16 VM I tried booting fails with the same issue, so I can't say for sure whether other VMs will fail as well.
3.) All VMs boot with BIOS and I did check these settings in XOA.
4.) The hosts have different CPU vendors (Intel -> AMD EPYC) but I doubt this is the issue because the VM does boot on the older kernel (as mentioned above.)
Has anyone ran into this issue? Any thoughts/clarifications I can offer?
Thanks in advance!
