[libvirt-users] Clock Sources under RHEL/Centos 5.x with KVM and libvirt
by Steven Ellis 27 Sep '10

27 Sep '10

I'm wondering under what circumstances the kvm-clock source is exposed to a guest. I've got a bunch of KVM servers running Centos 5.5 and some of the guests have are defaulting to jiffies or apic whilst some are picking up kvm-clock. These guests are a mix of 32bit and 64bit Centos 5.5. Looking at the virtual machine definition file there doesn't appear to be a difference between the guests with kvm-clock and those without. Any where else to look, or what configuration will expose kvm-clock to a guest. Steve -- Steven Ellis - Bulletin.Net Inc - http://www.bulletin.net

[libvirt-users] Unable to change guest vnc port in libvirt
by mmv＠eholod.ru 25 Sep '10

25 Sep '10

Hi all! I set in XML <graphics type='vnc' port='5901'/> But Libvirt assign first free port from 5900 and take 5900. Anb block access to host console vnc (tightvnc-server-module). Console access need not frequently. I do # service libvirt-guests stop;killall Xorg; service libvirt-guests start But it dirty hack Im use Fedora 13 # env LANG=en_US virsh version Compiled against library: libvir 0.8.2 Using library: libvir 0.8.2 Using API: QEMU 0.8.2 Running hypervisor: QEMU 0.12.5 I prefer possiblity to define for libvirt different base port for |autoport|. 5910 for example. Somebody know solution?

Is there an easy way to get a virtual server into the dormant state without waiting? QEMU command or libvirt cim call? Paul Oldfield 3605 Hwy 52 North Rochester MN, 55901 Tel: 507 253 1750 TieLine: 553-1750

[libvirt-users] Question on CPU pinning in Python
by Stanley, Jon [Tech] 23 Sep '10

23 Sep '10

Looking at the python API, once I have a domain object I can call domain.pinVcpu to pin a specific vcpu to a physical CPU. I found http://www.mail-archive.com/libvir-list@redhat.com/msg04562.html which mentioned some changes to the C API in the Python implementation, and was wondering if my understanding is correct. Say that I have a host system with 16 logical CPU's, 0-15. If I wanted to pin vcpu1 of a domain to CPUs 2 and 4, I would pass: domain.pinVcpu(1, (False, False, True, False, True, False....[and so on til I have 16 things])) In other words, pinVcpu accepts as arguments the vCPU that I wish to act on, and a 16 (or however many CPU's are present on the host) item tuple of True/False values, in the same order as the CPU's I wish to mask (for example, item 0 of the tuple represents CPU0), True meaning that the vCPU thread is allowed to run there, and False meaning that it is not. Just looking to confirm that my understanding of this call is correct. Thanks! -Jon

[libvirt-users] libvirt support for sheepdog file system
by Narendra Prasad Madanapalli 23 Sep '10

23 Sep '10

Hi Everyone, I am planning to extend libvirt to support sheepdog for qemu/kvm and found that storage code is placed in src/storage. Storing files in sheepdog is independent of file system and we just need to specify vm-name on qemu command ine. Here are the following comands used for creating and running a VM using qemu qemu-img create sheepdog:MyImage001 25G qemu-system-x86_64 sheepdog:MyImage001 I would appreciate if any one provide pointers on incorporating sheepdog functionality to libvirt. Thanks, Narendra.

Re: [libvirt-users] access VMX config on esxi with virsh
by frank dirks 22 Sep '10

Hi, you are right - the problem is specific to only that one vmx file - for other virtual machines dumpxml is working, as i found out. i am using esxi 4.1.0 and virsh 0.8.4. the machine was created using vsphere client, and was cloned and renamed afterwards - maybe that was the problem ... regards, frank > > Hm, that's strange.

[libvirt-users] correction
by Glynn D. Reynolds 21 Sep '10

21 Sep '10

I have corrected the error! Error: Sep 18 13:53:46 gdrenterprise libvirtd: 13:53:46.116: error : virInterfaceDefParseMtu:141 : XML description for interface mtu value is improper is not well formed or invalid To correct this error you will have to remove or correct the entry of virtual IP's added to /etc/sysconfig/network-scripts/ by the virtual application. Theory! I suspect that if you add the network interface with application that have non root privileges or you have configured /etc/access.conf. In additional to running selinix, root could be the one that may have the authority to add the network interface configuration. -- Glynn D. Reynolds <glynnreynolds123(a)gmail.com> GDRENTERPRISE
