I have 2 types of hosts as below ( each is 64 bits processor . number of
processor is not equal . First has 1G memory . the second 3 G memor):
IBM blade HS21 with Intel Xeon L5320 (1,86Ghz) . 8 processors (blade)
IBM desktop with Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz
I have generated an Ubuntu 8.10 client image on the first . It runs smooth
on the first via virsh . It runs ok on the second but not well via virsh
( define + start <xml> ). just by a direct : sudo qemu-system-x86_64 call
.
If I generate a similar image on the second host (using same .iso Ubuntu
CD image) then it runs on the first and second host smoothly via virsh
(define + start <xml>)
Is there an explanation for that ?
Also : please comment if the below qemu-system-x86_64 explicit image
start of a VM and the same done by a virsh command by : define + start
<.xml>
are equivalent and if not what change should I make to the
.xml file (below)
1. sudo qemu-system-x86_64 -hda <path/to/image/file> -m 512 -net nic,
model=e1000 -nic tap
2. The xml file
thanks
