Subject: qemu_capabilities: Format and parse new hyperv domcaps members
X-Git-Tag: v11.9.0-rc1~58
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0141f6544cda75d47eb35b95c10878793c22c187;p=thirdparty%2Flibvirt.git

qemu_capabilities: Format and parse new hyperv domcaps members

After previous commit the virDomainCapsFeatureHyperv struct
gained new members. Since virQEMUCaps struct holds a pointer to
such struct we must format and parse it to/from capabilities XML.
