Re: [Xen-users] Slow network speed with Xen 3.2-1
I had a similar problem and the solution was to disable checksum offloading in the domU. sh# ethtool -K eth0 tx off You can add this to your /etc/network/interfaces, too.. post-up ethtool -K eth0 tx off I also had to disable this in my dom0 for dhcp to work... cheers! b On Thu, Sep 10, 2009 at 2:19 PM, virtualroot wrote: > I'm getting a slow network speed (download/upload) domU and dom0 > limits in 10kbps/20kbps. > Booting a kernel without Xen, this doesnt happens > > /etc/xen/xend-config.sxp > (network-script network-bridge) > (vif-script vif-bridge) > (dom0-min-mem 196) > (dom0-cpus 0) > > cat /etc/xen/XXX.cfg > kernel = '/boot/vmlinuz-2.6.26-1-xen-amd64' > ramdisk = '/boot/initrd.img-2.6.26-1-xen-amd64' > > memory = '2048' > vcpus = '4' > > root = '/dev/sda2 ro' > disk = [ > 'phy:/dev/storage/XXX-disk,sda2,w', > 'phy:/dev/storage/XXX-swap,sda1,w', > ] > > name = 'XXX' > vif = [ 'ip=190.228.X.X,mac=00:16:3E:37:17:9A' ] > > root = "/dev/sda2 ro noapic acpi=off nopcmcia noagp nobluetooth" > extra = "3 xencons=tty" > > on_poweroff = 'destroy' > on_reboot = 'restart' > on_crash = 'restart' > > I use Debian 5.0.2 kernel 2.6.26-1-xen-amd64 > > ___ > Xen-users mailing list > xen-us...@lists.xensource.com > http://lists.xensource.com/xen-users > -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
