We have Solaris 10 VM in KVM (ProxmoxVE) how to check if Solaris is using all cores?

Question

I'm trying to figure out is VM Solaris 10 (which is virtualized with KVM on ProxmoxVE) using all allocated CPUs? Host HW is Dell poweredge r720.

And find a way how to check that for example gzip on large file is running in parallel?

This and this script are reporting only one virtual cpu/core.

I'm pretty much n00b when it comes to Solaris, and I have some linux skills.

Here is the kstat and prtdiag output

What are the values of sockets and cores in /etc/qemu-server/NNN.conf (where NNN is the number of your Solaris VM)? How many cores have you allocated to the VM? — HTTP500, Aug 12 '13 at 14:17
there is no config files for none of VMs in /etc/qemu-server/, but VM has alloceted 5 cores via WebGui. @JannePikkarainen tnx for pigz. — msvalina, Aug 13 '13 at 11:23

Additionally, You can use

psrinfo -pv

command to get number of physical processors/CPUs installed in your system.

Regarding CPUs utilization, run the gzip as you wish and then

mpstat

which will show you usage over all CPUs. By default, the output is sorted by CPU number. You should be interested in last four columns. If gzip runs in parallel on multiple CPUs you should see higher numbers in "usr" column for each CPU (time spent executing user code). If there is only one value higher and the other ones are around zero then it may mean that gzip is running on single CPU only.

Please keep in mind that this procedure assumes there aren't other CPU hog processes running on the system.

`bash-3.2# psrinfo -pv The physical processor has 1 virtual processor (0) x86 (chipid 0x0 GenuineIntel family 15 model 6 step 1 clock 2000 MHz) Common KVM processor ` And `mpstat` is showing only "usr" value around 90, same with `top` when I'm running gzip. I have also tried to change processor type in proxmoxVE from kvm64(defautl) to host which is xenon (sandy bridge) but then solaris wont boot. – msvalina Aug 13 '13 at 11:48
So you have only one CPU in the system available. – dsmsk80 Aug 14 '13 at 12:26
