Subject: Poor performance with qemu
Date: Sun, 28 Mar 2010 17:18:03 +0200 [thread overview]
Message-ID: <201003281718.03699.diegocg@gmail.com> (raw)
Hi, I'm using KVM, and the virtual disk (a 20 GB file using the "raw"
qemu format according to virt-manager and, of course, placed on a btrfs
filesystem, running the latest mainline git) is awfully slow, no matter
what OS is running inside the VM. The PCBSD installer says it's copying
data at a 40-50 KB/s rate. Is someone using KVM and having better numbers
than me? How can I help to debug this workload?
