Martin, et al, Sorry for the lag in response. So I started playing with the various virsh commands. Awesome. Been doing some reading and I believe I have some things configured not so well. As I stated earlier in the thread, we have all of the VM image files on one RAID5. Very fast machine. When using top, the load average is a stable "5.xx". No I/O wait. GB's of free memory. Swap has not been touched. Using vmstat, I am writing to the RAID5 volume at a constant 150MB/s and reading at a constant 275MB/s. With all of that said, here are some results from virsh commands: # virsh pool-list --all Name State Autostart ------------------------------------------------------ default active yes # virsh pool-info default Name: default UUID: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx State: running Persistent: yes Autostart: yes Capacity: 30.76 GiB Allocation: 2.10 GiB Available: 28.66 GiB Now, is that ok to have all of the VM's using a default pool? Or should a pool be created for each VM instance. I honestly am not even sure what a pool references...?... The more I read, the more I am moving away from thinking something in the OS is the cause of my sluggishness. Suggestions? Many thanks in advance, Tom On Thu, May 22, 2014 at 9:16 AM, Martin Kletzander <mkletzan@redhat.com> wrote:

Hi, Is there any way to get host OS information and host Storage in formations using libvirt API...? Rgds -Sijo
Check virsh help (most of the commands you probably want start with 'node' or 'vol'/'pool') or have a look at our hvsupport page [1] for virNode* and virStorage* functions.
If this isn't what you're looking for, specify your question in a better way.
