Can you check for any differences betwewn the newly created VM and the old one. Set an alias as follows: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Then: virsh dumpxml oldVM virsh dumpxml newVM Maybe somethhing can give a clue what is going on.

Dear Strahil,

 

Last strange discovery. Newly installed VM – same OS, same NIC’s – connected to the same VLAN’s. Both machines are running on the same virtualization host.

Newly installed VM – no network issues at all. It works flawlessly.

 

It is really very strange.

 

Best,
