Just pinging the server or pinging from the host OS outside of my network results in loss of packets. Occasionally my CPU is so taxed that network requests are stalled or cut out. I've given 256 MB RAM to my guest OS (Ubuntu). I believe my computer has 384 MB of RAM. I've tried running Ubuntu with the default 128 MB RAM too. I can't help thinking that there is something simply wrong here. Qemu takes 25% of my CPU just to sit idle. I was under the impression that it is supposed to perform much better? As it stands, VMWare 3.x on the same machine runs far better. Qemu is currently pretty much unusable for me. Is this pretty much just the way things are? Should I try running FBSD 6.1 and running Xen? If so, any guides explaining how to do that? Any general advice? I'd like to move away from VMWare since it seems flakey, instable, and has a questionable future on FBSD.
