[PATCH 02/13] qemu: alias: Allow passing alias of parent when generating PR manager alias

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

 



For use with blockdev the PR manager will be bound to a virStorageSource
rather than a virDomainDiskDef, so we will need to use the correct
alias.

Allow passing a string rather than the whole disk.
