Hi, we have significant network performance with issue with virtio_net in Debian Squeeze KVM guests, with more than one core assigned.
I test: > wget -O /dev/null http://mirror/proxmox-ve_2 .2-7f9cfa4c-28.iso KVM guest (4 core) with e1000 Squeeze (amd64): 64.3 MB/s KVM guest (4 core) with virtio Squeeze (amd64): 7.34 MB/s KVM guest (1 core) with virtio Squeeze (amd64): 75.3 MB/s Kernel used in KVM guest: 2.6.32-5-amd64 #1 SMP Sun Sep 23 10:07:46 UTC 2012 x86_64 GNU/Linux modinfo virtio_net filename: /lib/modules/2.6.32-5-amd64/kernel/drivers/net/virtio_net.ko license: GPL description: Virtio network driver alias: virtio:d00000001v* depends: virtio vermagic: 2.6.32-5-amd64 SMP mod_unload modversions parm: napi_weight:int parm: csum:bool parm: gso:bool Proxmox VE as KVM guest is not affected, also newer Debian Kernel (e.g. Wheezy) are working without problems. Any ideas? Martin _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
