Posted May 21, 2018 Anyone here have experience with OpenBSD 6.3 as a guest under libvirt? I've spun up a couple instances on my CentOS 7 KVM/libvirt host and I cannot seem to get more than roughly 100Mbps network performance from them. Using the virtio NIC I can sustain transfer rates of roughly 12 MB/sec. I tried switching to the e1000 NIC and performance was worse ( ~8 MB/sec sustained transfer rates with it) even though the virtual NIC indicated it had a 1000baseT full-duplex link. I did not try the rtl8139. Any ideas? 0 Share this post Link to post Share on other sites
Posted May 24, 2018 Huh, interesting. I run a similar setup on most of my hypervisors (Slackware though, not CentOS). I'm getting better than 12 MB/sec sustained on a big DB dump, but not gigabit speed. Are you also using a standard Linux layer 2 bridge for what the virtio device is connected to? 0 Share this post Link to post Share on other sites
Posted May 24, 2018 I have br0 set up that is used as the network interface for all of my VMs as well as management for the host itself. All of the other VMs I run (mix of CentOS and Debian) can sustain ~50 MB/sec transfer rates over the network, so it's weird. Only one network interface is currently assigned to the bridge interface. 0 Share this post Link to post Share on other sites
