You have been subscribed to a public bug: I'm running Ubuntu 8.10 amd64 on a host with hardware virtualization (4-core 2.6ghz AMD machine) using virt-manager (libvirtd) and kvm.
All VMs are 32bit (8.10 and 9.04) The 8.10 guests on this host can transfer at 20+ M/s to the host. (1000mbps speeds) The 9.04 guest, created the same way, is capped at 11M/s (100mbps speeds) I ran several tests with 1GB files (dd if=/dev/zero of=test bs=1M count=1024) r...@ubuntu904se32:~# scp test [email protected]:/tmp [email protected]'s password: test 100% 1024MB 11.9MB/s 01:26 r...@ubuntu810liveserv:~# scp test [email protected]:/tmp [email protected]'s password: test 100% 1024MB 24.4MB/s 00:42 r...@services810:~# scp test [email protected]:/tmp [email protected]'s password: test 100% 1024MB 22.3MB/s 00:46 Any suggestions for how to troubleshoot this further would be appreciated.
