[PATCH 06/21] qemuBuildHostNetStr: Stop using 'ipv6-net' convenience argument

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

 



In qemu the argument of 'ipv6-net' is split up into 'ipv6-prefix' and
'ipv6-prefixlen'. Additionally now that 'netdev_add' was qapified, only
the real properties are allowed. Switch to using them explicitly.
