Subject: [PATCH] qemu_capabilities: Change virQEMUCapsFillDomainCaps signature
|
|
|
|
Up till now the virQEMUCapsFillDomainCaps() was type of void as
|
|
there was no way for it to fail. This is, however, going to
|
|
change in the next commit.
|
|
|
|

|
(cherry picked from commit 2b2e4a7acff5574dd82bfbd61a638270f6be54ef)
