SIGTERM signal to qemu-kvm process
Hi I am using QEMU 0.12.1 as the hypervisor in my RHEL installation of 6.5. I wanted to know if there are any side-effects with respect to VM image corruption when i use SIGTERM signal to kill a qemu-kvm process which effectively stops my VM running on the host. Appreciate if you can provide me some valuable information in this regard. Thanks Jatin

Re: VM Performance using KVM Vs. VMware ESXi

Found this information from this link: http://wiki.libvirt.org/page/Virtio#Disk_.28block.29_device_driver I tried without upgrading the Kernel and as soon as i start my VM it got into Kernel Panic. I will try using virtio after upgrading my VMs kernel. Thanks for all the responses and

Total Threads used in a system
Hi I know we can get the total number of processes running in the system using the 'ps -A' command but is it possible to get the total number of threads running in the system ? Is this information exposed using any of the MIB's ? Thanks Jatin

Optimum Block Size to use
Hi All We use CentOS 6.6 for our application. I have profiled the application and find that we have a heavy requirement in terms of Disk writes. On an average when our application operates at a certain load i can observe that the disk writes / second is around 2 Mbps (Average). The block size set is 4k ******************* [root at localhost ~]# blockdev --getbsz /dev/sda3 4096
