Hi,
I was planning on using qemu to run several instances on various OSes on my
OpenBSD 5.0/amd64 server.
As a first try, I ran an OpenBSD 5.0/i386 instance using qemu-0.14.1p4:
# ifconfig tun0 link0
# ifconfig bridge0 add tun0 add bge0 up
# qemu -nographic -m 128 -net nic -net tap,ifname=tun0 -no-fd-bootchk -hda
/home/vm/monitoring.img
Then I configured munin-server in the vm to poll the amd64 server and the
local munin-node.
On the virtual machine side, I get:
# top -o cpu -n 1
load averages: 2.77, 3.35, 2.13 monitoring.tumfatig.net 22:54:30
42 processes: 2 running, 39 idle, 1 on processor
CPU states: 17.6% user, 33.1% nice, 8.8% system, 0.1% interrupt, 40.4% idle
Memory: Real: 31M/72M act/tot Free: 44M Cache: 22M Swap: 0K/259M
PID USERNAME PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND
568 _munin 84 10 6396K 5268K run - 0:57 48.68% perl
On the server side, I get:
# top -o cpu -n 1
load averages: 2.28, 1.72, 1.40 bagheera.tumfatig.net 22:55:16
96 processes: 93 idle, 1 zombie, 2 on processor

5764 root 64 0 207M 156M onproc/1 - 13:43 84.38% qemu
I read that kqemu is not available anymore but wondered if there were some
tricks to accelerate the Qemu instances ?
TIA,
Jo
