Subject: vz: added VIR_MIGRATE_PARAM_BANDWIDTH param handling
X-Git-Tag: v2.2.0-rc1~11
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2354266acf69393d533a7f461530da9afbf56f57;p=thirdparty%2Flibvirt.git

vz: added VIR_MIGRATE_PARAM_BANDWIDTH param handling

libvirt-python passes parameter bandwidth = 0
by default. This means that bandwidth is unlimited.
VZ driver doesn't support bandwidth rate limiting,
but we still need to handle it and fail if bandwidth > 0.
