any command is taking long time to execute

[P Arumugavel]

Hi Gurus,

I am facing a problem with a HP VM guest.

Running OS: HP-UX 11.31

VM : Version B.04.20.00

Problem: any command I issue is taking a long time. Due to this there were may jobs are hung .

Even ssh session is taking long time to give the login prompt ( I already checked the /var/adm/wtmp and btmp), also it takes for login.

Ping result also indicates no issue (response time is good)

Also done a general health check (bdf, ioscan, top, glance, sar..), everything looks to be normal.

Not able to have any clue about this issue, can anyone advise if you have a same experience.

Thanks,
Vel

P.S. This thread has been moved from HP-UX > sysadm to HP-UX > virtualization.

What type of commands?  How many CPUs are assigned to the guest?

Are all guests this slow or just this one?

What does "swapinfo -tam" show?

Anything obvious with uptime and top?

What's the state of the VM host?

If your VM host is overcommitted (e.g. the guests in it have more virtual CPUs total than the host has physical CPU cores) and/or another VM guest is doing a lot of I/O operations, your guest might slow down because there are not enough physical CPU or I/O capacity in the host to satisfy all the guests.
