[PATCH] libxl: mark domain0 as persistent

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A Xen domain0 is better described as a persistent domain. Mark it
as such during intialization.

I noticed this while debugging a libvirt-guests issue. The list_guests()
function filters domain0 with

echo "$list" | grep -v 00000000-0000-0000-0000-000000000000

If domain0 is the only item in $list, the grep returns 1, causing
a failure of the stop operation when action is suspend. This
patch fixes the libvirt-guests issue, but I can also send a patch
to improve the filter if desired. E.g.

echo "$list" | sed "s/00000000-0000-0000-0000-000000000000//g"
