Yes, it is. Quota is a filesystem feature, not a xen feature.

You seem to be using xfs, so 'man 8 xfs_quota' will give you the bits you 
need, like this one:

QUOTA ADMINISTRATION
  The  XFS  quota system differs to that of other filesystems in a number of
  ways. Most importantly, XFS considers quota information as filesystem
  metadata and uses journaling to provide a higher level guarantee of
  consistency. As such, it is administered differently, in particular:

  1. The  quotacheck  command has no effect on XFS filesystems. The first time
     quota accounting is turned on (at mount time), XFS does an automatic
     quotacheck internally; afterwards, the quota system will always be
     completely consistent until quotas are manually turned off.
