Hi, Netperf tells me that a KVM VM using a bridged connection to a system across the Gigabit LAN sees on average about 1/10th of the bandwidth the host sees. This is on very lightly loaded hosts, although with multiple low-use VMs. I've tried adjusting the CPU throttling after seeing that mentioned as a possible factor in slowing down a bridge, but it has not much if any effect here.
Is there a good guide somewhere to what might make a difference with this? I recall the kernel recently adding a new alternative for handling VM interfaces, but can't recall what it was called. Would that be a marked improvement? Is it supported by libvirt? Thanks, Whit _______________________________________________ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
