The rules for CPU count in XP-Pro are as follows: the physically chip that you install on your motherboard is referred to by M$ as a CPU. XP-Pro will only allow up to two CPUs. Each physical CPU may have as many processors on it as will fit. M$ calls these processors "cores". XP-Pro does not limit cores as long as they do not span more than two CPU's. My host machine has one CPU and four cores (eight if you consider the hyperthreading). KVM is presenting my XP-Pro guest multiple CPUs, not cores. XP will not use more than two CPUs by design. What I am after is a way to have KVM present my guest one CPU with four cores. Not four independent CPUs. I have attached /proc/cpuinfo from Fedora Core 16 guest, along with my /proc/cpuinfo from my host. What am I doing wrong?

Given a bit of time I can give you the full report if that would help. My host CPU is an i7-960 (four real cores, eight hyperthreaded cores.) -T

[libvirt-users] How to use virt-install and http to install openbsd VM in KVM?
by Li, David 30 Nov '11

30 Nov '11

Hi, Not quite sure if this is the right forum for this question. My requirement is to http boot openbsd in KVM. This works fine with RHEL6 guest install but not with OpenBSD. I loop mounted the openbsd installer on the http server. My Http server directory looks like: [root@uefiserver vm-openbsd]# ll total 5 drwxr-xr-x 3 root kmem 2048 Aug 17 09:35 5.0 drwxr-xr-x 2 root kmem 2048 Aug 17 09:35 etc -r--r--r-- 1 root root 82 Aug 17 09:35 TRANS.TBL My browser can see this directory no problem. And KVM output: [root@lid-hs22-2 ~]# virt-install --hvm --connect qemu:///system --network=bridge:br0 --location=http://10.10.36.134/vm-openbsd/ --name=vm5-openbsd --ram=2048 --vcpus=2 --os-type=unix --file=/var/lib/libvirt/images/vm5-openbsd.img --file-size=20 ERROR Error creating cdrom disk: Could not find an installable distribution at 'http://10.10.36.134/vm-openbsd/' The location must be the root directory of an install tree. [root@lid-hs22-2 ~]# IS this supported? Did I use the right semantics? Thanks. - David

[libvirt-users] permission denied when setting up VMchannel with libvirt

Hi, I am trying to set up vmchannel between the host and guest os. However, "sudo virsh start vm1" always gave me this error: ************************************************************* error: Failed to start domain vm1 error: internal error Process exited while reading console log output: char device redirected to /dev/pts/5 bind(unix:/tmp/foo): Permission denied chardev: opening backend "socket" failed ************************************************************* Related xml is: ************************************************************* <channel type='unix'> <source mode='bind' path='/tmp/foo'/> <target type='virtio' name='channel.port.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> ************************************************************* I can succeed while I manually run the guest os by: ************************************************************* sudo kvm -device virtio-serial \ -chardev socket,path=/tmp/foo,server,nowait,id=foo \ -device virtserialport,chardev=foo,name=org.fedoraproject.port.0\ /path/to/vm1.img ************************************************************* I also noticed that libvirt is able to create socke /var/lib/libvirt/qemu/vm1.monitor every time. I can't win even I change the unix socket path to "/var/lib/libvirt/qemu/foo" Any information will be appreciated! Thanks, Will

[libvirt-users] virt-manager / ssh (publickey)
by Shaun Glass 29 Nov '11

29 Nov '11

Good day All, I have experienced the following ... I have a rhel 6.1 server running qemu-kvm. I have setup my desktop for a publickey login (root user) to said server so that I may manage the server (qemu-kvm) via the desktop with virt-manager. However, I connect just fine, but cannot create vm's. I get : "No hypervisor options where found for this connection" My laptop does run qemu-kvm via virt-manager and so I decided to setup a publickey login as before and guess what ... I can create vm's. It seems virt-manager bases the creation of vm's based on the hardware / software of the machine it is launched from and not the machine it is connecting to. Is there a workaround / config change etc that can be done so that virt-manager uses the hardware / software configuration of the system it is connecting to ? Regards Shaun Glass

To whom it may concern, I send this email to this list to report that I've released a small application for Android that uses libvirt over SSH. It is still under development and it has little features (Start/Destroy/Info) but I'll add more soon.

[libvirt-users] Failed to start a "virtual machine " service on RHCS in CentOS 6
by xuteng 25 Nov '11

25 Nov '11

Hi， All: I have two physical machines as KVM hosts (clusterA.RHCS and clusterB.RHCS) , an iscsi target set into GFS. All I want is a HA Cluster which could migrate all the virtual machines on a node to another when the first node failed into some error status. So I created a cluster "cluster" using RHCS ,added the two hosts into the cluster . created a fence device . for every virtual machine on clusterA , create a service ,added a resouce which type is "virtual machine" , and set it's properties. But when I start the service ,I got these errors in /var/log/message : [root@clusterA ~]# tail -f /var/log/messages Nov 24 16:19:29 clusterA libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: Permission denied Nov 24 16:19:30 clusterA modclusterd: startup succeeded Nov 24 16:19:48 clusterA rgmanager[6754]: Executing /etc/init.d/httpd status Nov 24 16:19:56 clusterA modcluster: Starting service: wuguang-xp on node Nov 24 16:19:56 clusterA rgmanager[2198]: Stopping service vm:wuguang-xp Nov 24 16:19:56 clusterA rgmanager[6850]: Using /etc/libvirt/qemu/wuguang-xp.xml instead of searching /etc/libvirt/qemu Nov 24 16:19:56 clusterA rgmanager[6906]: xend/libvirtd is dead; cannot stop wuguang-xp Nov 24 16:19:56 clusterA rgmanager[2198]: stop on vm "wuguang-xp" returned 1 (generic error) Nov 24 16:19:56 clusterA rgmanager[2198]: Marking vm:wuguang-xp as 'disabled', but some resources may still be allocated!
