RHEV: Why does a hypervisor lose networking for a few minutes intermittently, during VM start/stop/migrate/create operations?
Issue
- A RHEV hypervisor host (RHEV-H or RHEL based) loses connectivity to RHEV-M during VM operations (start/stop/migrate). After a 5-10 minutes, the host is reachable again.
- A normal RHEL5 (as KVM host) can have similar problem too.
Environment
- Red Hat Enterprise Virtualization (RHEV) 2.1
- Red Hat Enterprise Linux 5.5
- libvirt-0.6.3-33.el5 (or before)
