Hello all.
We are moving from Xenserver 6.5 environment to KVM because we can't use 10gbe speed in our VM's so we decided to test KVM.
To inicial test I've create script, using qemu commands, to build two VM's and test the nic speed.
Each VM has one nic, using virtio, into it own bridge. In this bridge we associate one 10gbe physical nic.
They can communicate each other.
When we try do a copy, through SCP, the speed is 300mbps. And if we open another copy this speed been the half.
Assuming you mean 300MB/s then I suspect you are CPU bound as that's a lot of crypto operations for scp. Install iperf http://pkgs.repoforge.org/iperf/ Run iperf -s on one vm and iperf -c <ip of other vm> on the second one I have benchmarked KVM with openvswitch at over 15Gbit/s on fairly standard hardware (Second gen i5 desktop) - -- Tim Fletcher <tim@night-shade.org.uk> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBCAAGBQJU58jPAAoJEN542XhkDoF1ZBYH/2SjA93rtOwuM0vh81/ctlU/ Riws/r8R51LXpz5QICk9GSWNeGfGlvRUq3XVvteBX0GSpknewg3Aa7Jy7lUeXUp+ ULnjg28YlytgpVGzD5LKmzoW809ZwoVLHj0uVQ9pdDXa+6N1ztXR/O3fsV+4GaX9 lVHoX3HrRm/wK/Y/zyXplAu4Ylx61KDmZeBkuaL75XHXsIFbpUqhYOMlNRLsg4rr buHcDZZNCXp6eMRRHJTdde9C53rky1JECVgctubVyxlI2Uu26CpDKsqR9AKLTPKm mxb32BMEpajbckGiTSHH89XWg0CBy5XMc1G6oGGOcWjhhosanCtVorHGq+xQ/Uw= =AOM8 -----END PGP SIGNATURE-----
