Moving a VM to a new host in Xen Orchestra

Danp

Yeah... that's a current XS limitation that the VM must be running in order to migrate it.

Danp

Haven't seen the 2nd error before. Are you running the latest version of XO?

Perhaps this thread will help.

@Danp recent enough I would hope, not on 4.14 yet. xo-web 4.13.0

could be the culprit. now trying to find out how to set/change the default SR

@Danp yup, that was it. now onto troubleshooting the next set of errors. First one was quite obvious, destination host didn't have enough RAM. The other two though I'm not finding a table of what those feature codes translate to.

vm.migrate(...) [601ms] =!> XapiError: HOST_NOT_ENOUGH...36296192)

vm.migrate(...) [738ms] =!> XapiError: VM_LACKS_FEATUR...cdfd0954)

vm.migrate(...) [639ms] =!> XapiError: VM_LACKS_FEATURE_SU...1cdfd0954)

Am I missing some vital info, it seem to be truncating some details there when I run the following to get those results

sudo systemctl status xo-server.service

Danp

To eliminate the truncation, add the line verboseApiLogsOnErrors: true to the file .xo-server.yaml, like this:

sudo sed -i "$ a verboseApiLogsOnErrors: true" /opt/xo-server/.xo-server.yaml

Then restart xo-server.

From the API docs:

This means your VM doesn't have tools installed or your guest doesn't support "soft" calls to suspend/shutdown it (but hard reboot/shutdown always work, that's like pulling the power cord).

thanks for the tips. i didn't have vm tools installed on some hosts but didn't have a chance to check again today so perhaps tomorrow success after ensuring tools are installed on all hosts. they are all on HP Proliants and just Ubuntu/Win hosts so nothing unusual that I'd expect to not support this I hope.
