John,
I just applied your suggestion
#virt-install -n solHVM1 --hvm --vnc -r 10240 -f /xvm/solHVM1/root.img
-s 16 -c /iso/sol-os-platform-dvd.iso --vcpus=4
while this was running, on another terminal window I used virsh to
vcpupin the domain CPUs. Below the ouput from xm list
However, no improvement , it is actually slower, this time it stopped at
"Setting up Java, please wait". After 8 minutes, it continued to the
"Extracting Windowing system" step.
Do you know if you have this issue when using Sol10u4 instead of snv_75a
for the domU ??
Thanks,
J. Cardozo
