Re: Host crash
Looks like double free or similar. Try adding the kernel boot parameter slub_debug=ZFPU. Will do. Meanwhile I got the same error on the other host. I was able to login via ssh though.

Host crash
Hello, I ran into a crash today while I tried to log into one of my servers. I noticed ssh didn't respond at all. All virtual machines were running ok though. I had one terminal open to the server and it was running ok except ssh didn't work. I'm not quite sure if this is kvm related but I was hoping you experts could figure out what went wrong.

Re: Can I simulate a virtual Dual-Head Graphiccard?
Is this possible with kvm? Either simulate a dual head mapping to one wide SDL/VNC display. Or having two SDL/VNC displays? No. It was brought up before on the qemu list I believe. I think the gist was that qemu didn't support more than one vga card. Spice (www.spice-space.org) can do this. I just tested it and works well. Too bad spice isn't included in qemu-kvm yet. -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Create group kvm and add users who should be able to control VMs - usermod -a -G kvm username . Set /dev/kvm permissions - /etc/udev/rules.d/91-permissions.rules - KERNEL==kvm, GROUP=kvm . To be able to use USB devices edit /etc/rcS.d/S02mountkernfs.sh Change line domount usbfs usbdevfs /proc/bus/usb usbfs -onodev,noexec,nosuid to domount usbfs usbdevfs /proc/bus/usb usbfs - nodev,noexec,nosuid,devmode=0660,devgid=117 (117 is gid of the kvm group) .

Also nice levels and CPU affinity are defined here. /etc/kvmctl/global.conf Path defines go here /etc/kvmctl/cfg/* Configuration files of the virtual machines. See example.cfg for instructions. Utility scripts --- /usr/local/bin/kvmctledit Is used to edit vm.conf. Simply starts $EDITOR. /usr/local/bin/kvmctl_fixperm Scans all config files for disk images and makes sure they are writable by kvm group. Works for files, lvm volumes and iSCSI volumes. /usr/local/share/doc/kvmctl/kvmctl.init Init script that can be copied to /etc/init.d. Manages virtual machines starting and stopping automatically during boot. Few notes - - Make sure you have configuration for each virtual machine defined in vm.conf - Edit /etc/qemu-ifup and make sure it uses same bridge names your system has - Don't use tabulator after virtual machine name in vm.conf Thats about it. Give it a try and let me know if you find it helpful. Most likely there are bugs but it works pretty well for me.

Re: Question about limiting KVM cpu usage

In other words, if I am running four guest servers and something on one of them begins to use a ton of cpu, I don't really want it to slow down all the others. Is the only way to do this by limiting it to one cpu core? Granted, I would prefer that it have access to full computing power if no other guest needs it. Thanks for any advice.

New version of my kvmctl script
For some reason I couldn't reply to my previous post... But here is a new version. Now with version number! :) Changes: - includes init script /etc/initd.d/kvm which starts and stops virtual machines when booting and shutting down the host. Shutting down the guest is done by sending system_powerdown to the guest. If the guest doesn't powerdown in 120 seconds (adjustable) it will be killed. - kvmctl can set vm to start or not to start during boot (kvmctl vmname onboot yes|no). Without yes/no script shows whether VM is started on boot or not.

Re: New version of my kvmctl script
After quick googling I renamed the script/product/whatever to virmactl (VIrtual MAchine ConTroL).

Control script for kvm
I think pretty much everyone has made their own so here is mine. Few features: - Can start, stop, reset etc virtual machines - Can set niceness level (I/O, CPU) and CPU affinity - Handles tap devices and VNC displays Files and what they do... kvmctl - main script. does all the work kvmvmedit - script to edit /etc/kvmctl/vm.conf /etc/kvmctl/global.conf - files and directories /etc/kvmctl/vm.conf - list of virtual machines and their VNC displays, MAC address etc /etc/kvmctl/networks.conf - network configuration /etc/kvmctl/conf/* - configuration files for virtual machines /etc/qemu-ifup - script to bring up network devices /var/run/kvmctl - directory for monitor sockets, pid files and file containing VNC display number /var/log/kvmctl - log files There are some documentation in the configuration files that might be helpful. TODO: - Currently must be run as root. Get over this limitation. - ONBOOT flag to start certain virtual machines on boot. Also gracefully shut running vms on reboot/shutdown of host - Fix bugs Licensed under GPL2. And then the standard disclaimer... It does the job for me but in case it doesn't work for you or even breaks things badly you are the one to blame.
