similar to: KVM or Qemu

As a Systems Administrator, I would like to grant permissions to a certain VM using unix groups. In this example there is a hypervisor with VMs A,B,C,D and there is a group called fortadmins. The solution I am searching forI would just allow fortadmins to use libvirt/virsh commands on VM D. Does libvirt/virsh provide any way to easily accomplish this goal? Regards, Jamie Ian Fargen

Hi,guys I wanna to get the disk snapshot size, but found nothing libvirt commands related,except qemu-img. I create two disk snapshots, but nothing return its' size [root@cskvm01 qcow2]# qemu-img info /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 image: /mnt/e6758700-af68-3c06-ade3-53f5f9b93507/e2cf6551-0d2c-4382-a86c-8ba633954ff2 file format: qcow2 virtual

They're *internal* qcow2 snapshots (original and delta are on the same file). A quick example of disk

Kashyap: I have not tried integrating your guest xml but I will look over it today when I get a chance. Thank you. Martin: Below is the output from /proc/cpuinfo.

Hey! I have some RHEL6 hypervisors and the VMs are in raw qemu image files in a local raid array linux raid + lvm + ext3. When a kernel update is installed a reboot is necessary, usually it has been more than 180 days since the last reboot and the file system is fsck'd and this takes 2-3 hours. I am curious to know if there is any documentation that addresses the pro's and con's of

Hi, I've been working on trying to figure out why my virtual machine keeps crashing when I don't believe I have a hardware problem, and I believe I might know why. As I'm relatively new to this, I believe I may have misconfigured the XML file to try and maximize the CPU features that are available to the guest from the host. I have an Intel Xeon E3-1240 3.3Ghz quad-core. How can I

Hello List Mates, I don't know if here is the right place for this question if it's not I will appreciate it if you can point me to the right mailing list. I have successfully installed KVM on my x86_64 laptop, however I am getting the following error when I try to connect "QEMU" from the Virtual Machine Manager Error polling connection 'qemu:///system': internal error

This patch adds the necessary KVM specific code to allow KVM to support the CPU halting and kicking operations needed by the queue spinlock PV code. Two KVM guests of 20 CPU cores (2 nodes) were created for performance testing in one of the following three configurations: 1) Only 1 VM is active 2) Both VMs are active and they share the same 20 physical CPUs (200% overcommit) The tests run

hello , thanks for comments . I tried now with force options for CPU flag which were not supported . Now the command with non fully supported CPU model gets executed , But i am surprised to see that still Guest cpu model is not changed and still same as host cpu model(SAndy Bridge) Why don't i see the model as HAswell now , could you please comment. Command used : virt-install

Good Afternoon, I was curious to know what happens to running guests when the qemu-kvm rpm is update via yum. I assume that the current qemu processes would be running the old binary, but the new processes would be started using the new binary. Please let me know if this assumption is correct.

Hi all. What right way to protect ip/mac spoofing for guests withnount dhcp and other 1 ip per guest?
