Hi.
I've a Debian6 server, running kernel 2.6.32-5-xen-amd64, Xen hypervisor
4.0.1-2.
It runs 2VM, an HVM firewall and a PV Ubuntu 10.04.
I'm experiencing terrible network performances on the main interface, shared on
both VMs and used as br0 on the dom0.
At first, I'm seeing the issue that network is stuck for some 20/30 seconds
when the HVM machine boots. But that's not a big deal, since hopefully it won't
boot often.
Now I'm having this trouble that causes the VM not to answer to network
requests, i.e. samba locked, other web services not responding... After some
time everything comes back to normal.
The network card is an onboard Broadcom Corporation NetXtreme II BCM5716
Gigabit Ethernet.
I see no error on syslog, dmesg, xend.log, xend-debug.log, and I don't know
where else to search!
Any adivce on where to look at?
thanks
