Subject: libxl: don't set hasManagedSave when performing save
X-Git-Tag: v4.4.0-rc1~188
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ac4a12db715cdb764281cdb89cabd478f8ec9d09;p=thirdparty%2Flibvirt.git

libxl: don't set hasManagedSave when performing save

libxlDoDomainSave() is used in both the save and managedsave code
paths but was unconditionally setting hasManagedSave to true on
success. As a result, undefine would fail after a non-managed
save/restore operation. E.g.

virsh define; virsh start
virsh save; virsh restore
virsh shutdown
virsh undefine
error: Refusing to undefine while domain managed save image exists

Modify libxlDoDomainSave() to take an additional parameter to
specify managed vs non-managed save, and change callers to use it.
