What does "lose a NIC" mean? Does it mean that device doesn't show up at all, and is not apparent with "/sbin/ifconfig -a" ? Or does it mean that the device is not properly configured with IP address and connected to the local network? I've certainly noticed with various virtualization systems and CentOS 6 that sometimes DHCP doesn't get configured in the very short time between the VM booting and the prompt being available. It always recovers with a "/sbin/service network restart". > I have configured 4 NIC on the Virtual host two passthru and 2 virtual, on > start most time i lost a virtual NIC :-( > > So after a reboot I have to check always is all running and working.? > > with a "virsh reboot xxxx" in the most time it come back ? > > Have any a Idea why ? > > I found nothing in the Logs :-(. > > -- > mit freundlichen Grüßen / best regards, > > Günther J.
