FreeBSD srv.mydomain.net 8.2-RC2 FreeBSD 8.2-RC2 #1: Sun Jan 23 12:49:35 EST 2011 alex at nospam.nospam.nospam:/usr/obj/usr/src/sys/custom-server amd64
I can report this issue is also present in 8.1/amd64 (and also occurs with the stock GENERIC kernels in both releases)
I am running FreeBSD on my VPS. The host is using XEN HVM.
There is an unusually high collision rate being reported on the network interface:
Name Mtu Network Address Ipkts Ierrs Idrop Opkts Oerrs Coll
re0 1500 <Link#1> 00:16:3e:f0:8b:6c 136929 0 0 104042 0 104036
So, out of 104042 packets transmitted, collisions were detected on 104036 of them.
I thought that perhaps this may just be a XEN related issue until I ran into this article on the web:
This seems to be the same issue, but when running FreeBSD under KVM. Same network interface (re). Is this likely to be an issue with the "re" driver under virtualized environments?
Run FreeBSD 8.1/amd64 in a XEN HVM environment
