It seems macvtap driver works better. I had no more problems since I use it instead the normal bridge tools.
Someone should take a look to this problem since macvtap has it's own problems, like host is not seeing hosted machine. I had to do the KVM subnet trick to enable a subnet for communications between host and vm. At least network gone no down anyway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255516 Title: Network access broken to some hosts after some usage...
