Subject: Improve filtering of Xen domain0 in libvirt-guests
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=8599aedd434a2843dca7fae37bd397f07a584c1a;p=libvirt.git

Improve filtering of Xen domain0 in libvirt-guests

The list_guests function in libvirt-guests uses 'grep -v' to filter
Xen domain0 from a list of guests. If domain0 is the only item in
the list, 'grep -v' returns 1, causing the 'stop' operation to fail
when action is 'suspend'. Improve the filtering by using sed to remove
domain0 from the list of guests.
