Hello, i´ve done 2 vm with qcow2 disks and created them with qemu-img with prealloc=metadata. Virt-Manager shows me under the performance settings for the Storage, Cache= Hypervisor Default IO= Hypervisor Default Is this the best setting? Or do i choose "native" IO on prealloc=metadata created disks? And do i have to change Cache too? The Virtualisation Host is gento linux, the

Hi List, i installed qemu-agent on a windows server and it is working as expected. I can send via virsh commands. I already performed successful an online backup of an windows server. Now my question is, is it possible to execute commands on the windows server via qemu-agent? I want to shutdown the MSSQL Service before doing backups. Is that possible? i dont find any helpful pages in net.

This might be related to the configuration of the virtual machine. A machine configured to have cpu X might not start up when it is changed to cpu Y. We also observed that a windows host does not boot on a ubuntu host with the default kvm configuration.

There were some fixes related to iptables/nf_tables in libvirt in recent releases, so it might just solve that for you. >

Hello all, I have already use xen for about a year. I use recently released Opensuse 11.3 (use Xen 4.0) for my experiment. I want to run 3D test in HVM(windows xp), so I want to use VGA passthrough technology. But there is something not work properly. I google a lot of time, it says, I/O virtualisation should be enabled, but I can solve it. I run "xm dmesg" command, in the

Hi, I used to use KVM for virtualisation and have now moved back to it, but I have a problem. When i used to install the guest machine with virt-install i used to use the -x "extra args" part to set the console for the install and guest, but it no longer works. Here is the command i use: virt-install -n server01 -r 512 --os-variant=virtio26 -c /isos/c5u5.iso --nographics

I have a chipset which supports VT-d (Intel X58) and, according to my motherboard manufacturers, VT-d is enabled in the BIOS and listed as "Intel VT." The problem is that xm dmesg shows "I/O virtualisation disabled" and I get this error message when I try to create a domU with a pci device assigned: ''Error: failed to assign device: maybe the platform doesn''t

Hi ! I'm about to deploy a new server that will host several virtual host for mainly website hosting purposes. My server will be a Xeon 3440 or 3450 with 32 gigs of ram (the max of that board). So I will have 8 logical cores. At the moment, I don't know how many vms I will have, in the order of 5 or 6. I am quite new to managing VMs, I did play alot with them over the course of the

Hi, I run a small company and I would like to virtualise our setup. My internet provider offers a cloud server running CentOS. The server is managed by vmware software, they haven't been able to tell me exactly what. I wanted to know is it possible to virtualise such a setup, and Have CentOS running as the virtual OS that every client sees. Is there a solution similar to vmware view + client

I would like to run multiple copies of an application on a PC with multiple remote dumb clients. It would seem to me that running Xen would be a sub-optimal solution as I would need a copy of the OS running for every copy of the application, but I was wondering whether a subset of Xen or Xen techniques could be used. There are 2 barriers to running multiple applications with remote access: -
