Hi,
I'm running a Solaris xVM using release 75a on a Sun X4600 with 8 AMD
dual core cpus, 32 GB RAM
I created a Solaris PV domain with the parameter --vcpus=4 and the
installation was very fast and works fine. If I run xm list, I can see
that my PV domain has 4 VCPUs.
#xm list
Name ID Mem VCPUs State
Time(s)
Domain-0 0 11284 16 r----- 15870.0
solarisPV 1 4 9305.9
However, if I try to create a HVM domain with parameter --vcpus=4 the
installation is really slow. The OS boots, I can select that it is a
Solaris Express Installation and that is an interactive one. It checks
the devices, but the systems hangs at the point where it says
"Extracting Windowing system" just before prompting for the vncviewer
password. After half and hour of wait, there is no progress. Here is
the command I'm running:
virt-install -n solarisHVM --hvm --vnc -r 10240 -f
/xvm/solarisHVM/root.img -s 16 -c /iso/sol-os-platform-dvd.iso --vcpus=4
I run truss against the virt-install process and it is sleeping. prstat
-mL shows not activity, all processes sleeping, no I/O activity is
reported by iostat.
If I run in another window xm list, I can see that my HVM domain has 4
Virtual CPUs, however, the system is hanging there, no progress.
If I run the same command but without the --vcpus=4, I pass the
"Extracting Windowing System" message within 30 seconds. I get the
vncviewer connection working and can setup the OS. After 15 minutes the
installation is complete. During the installation prstat -mL shows
qemu-dm on top of the list with CPU utilization greater than 25%, I can
see alot of activity from iostat while files are installed.
I do not understand, with 1 VPU installation finishes within 15 minutes,
while with 4 VCPUs the installation does not pass the Extracting
Windowing system after 30 minutes.
Has anybody have similar issues, any hints on how to make it work faster
? Am I missing other parameters ?
How can I configure 4 VPUS for an HVM domain such that when I run
psrinfo within the domain I see 4 CPUs ??
Tips, best practices are appreciated.
Thanks,
