I was slightly confused about this thread until I realized you were using static IP config on your VM's... Why do people do that? I have an extra step of picking up the HW address (or setting the HW address when creating the VM) and putting it into my dhcp configuration, but then I have al

[CentOS-virt] Xen domU default gateway missing/ARP table full

2009-11-18 Thread Ken Bass
I have been trying to figure out why my domU NIC becomes unreachable (could not even ping) at various times. (Normally when the server was trying to update clamav from the various busy mirrors at 4am). There also seemed to be some latency when connecting which I chalked up to it being a virtual
