Do not search xenstore for disk device IDs
|
|
|
|
Disk devices can be referenced by name in Xen, e.g. when modifying
|
|
their configuration or remvoving them. As such, don't search
|
|
xenstore for a device ID corresponding to the disk device. Instead,
|
|
search the disks contained in the domain definition and use the
|
|
disk's target name if found.
|
|
|
|
This approach allows removing a disk when domain is inactive. We
|
|
obviously can't search xenstore when the domain is inactive.
