[one-users] ONE 3.2 VM Management issues

Thu Jan 26 07:29:54 PST 2012

Hi,

The no_root_squash configuration is actually required, see the Shared File
System guide [1]. Even if qemu is executed as oneadmin, I think libvirt
still needs this parameter.

After a 'onevm shutdown' command OpenNebula sends the ACPI signal to the
guest VM, and if it does not disappear after a fixed timeout, it is assumed
that the signal was ignored and the VM is still running. You might want to
check if the acpi daemon is properly configured.
Or you can use the 'onevm cancel' command to perform a hard shutdown, in
this case a 'libvirt destroy'.

Regards
