reboot of host does it stop or kill running VM's?
-
@Danp I run "reboot" after ssh'ing into it and it rebooted. The VM stopped as expected, it rebooted and the VM restarted.
I just don't know if it was shutdown or powered off... But it seemed to just have been powered offl -
@manilx P.S. Coming from proxmox where I rebooted the host (after an update) and it shutdown the Vm's gracefully before rebooting.
-
It sounds like you were connected to the VM instead of the host.
What does
uptimereturn now on the XCP host? -
@Danp No. I SSH'ed into the host and entered "reboot".
Uptime is correct with the reboot time. -
@manilx said in reboot of host does it stop or kill running VM's?:

That is certainly an option here as well, but you need to use the correct process to reboot the host. Easiest way is using XO. Otherwise, there are a variety of host commands offered by
xe. -
@Danp OK, got it:
xe host-disable host=xxxx
xe host-reboot host=xxxxreboot on the cli just hard reboots the host on the OS level.
-
@manilx Maybe I am wrong, but I still think VM's are shutdown gracefully. If you look at the
Pool Taskview in XO and issue the reboot command while SSH`ed into the host, you see the shutdown for a second or two:
hp740 is the host that gets rebooted and hp_d12_s and hp_d12_c are two debian VMs on that host. Both VMs have the guest tools installed.
-
@gskger I tried this again with a bigger VM (longer to shutdoen) and yes, you're right, the VM's are gracefully shutdown. Great!
Same as in proxmox. -
@manilx If the VM has no guest tools installed (like this Windows VM), the host will perfom a hard shutdown of the VM:
So it is a good idea to have the guest tools installed.
-
@gskger Yes, all my VM's have guest tools installed, Windows/Linux. It's quite the "requirement".
