Sijo,

Pertaining to virt-manager and virsh sluggish behaviour after a clone operation:

Thanks for your response.

Honestly I do not know what "host Storage in formations using libvirt API" means.  Sorry.
I use virt-manager and virsh to do everything within KVM.  If there is something better or
another product/app that will enable me to drill down into the system...let me know...

However, perhaps this can help:

We are running CentOS 6 (Update 5) 64 bit - patched as of 11 April 2014.


I create the virtual machines with the virt-install command using the --file switch and lay the system images of the vm's on the RAID5.
The RAID5 uses ext4.  The I/O to that volume is nice. We currently are running twenty-six (26) VM's.  There is no I/O wait.  The system
has been up for thirteen (13) days.  The load index (top) is between 1 and 3.

Also, I have the following kernel tweak in /etc/sysctl.conf:

vm.drop_caches = 3

NOTE: Writing to this will cause the kernel to drop clean caches, dentries and inodes from memory, causing that memory to become free;
           this helps to mitigate dipping into swap.

Thanks in advance for everything,

Tom

Hi, 
Is there any way to get host OS information and host Storage in formations using libvirt API...?
