Subject: [PATCH] conf: Factor out vcpus parsing part from

Extract vcpus parsing part from virDomainCachetuneDefParse into one
|
|
|
0a7476 |
function called virDomainResctrlParseVcpus. So that vcpus parsing logic
|
|
|
0a7476 |
can be reused by other resource control technologies. Adjust error
|
|
|
0a7476 |
message and use node->name so that the error message can fit to all
|
|
|
0a7476 |
technologies.
