As planned the new release is available at: ftp://libvirt.org/libvirt/ It is a rather large release with near 400 commits included. From an user point of view the main improvement is likely to be when using migration as various work has been done to extend the protocol and to avoid having the migration command stop other concurrent operations (like virsh list). See below for a number of

Hi techs, Could you please explain or refer me to documentation where I could find a description of global_quota schedinfo option. Someone told me that it could mean a cpu limitation in percents like: global_quota : 25000 (does it mean cpu limit % set to 25 ?) Is it true? What other parameters mean in below output? I didn't find any related documentation at libvirt.org. Could you help me

Hi, I have two KVM host: h1 and h2, both of them mount an NFS directory as a shared storage. I can save (virsh save <domain> <file>) a domain in h1 to a state file in the shared storage successfully, but failed to restore it from h2 with the following error message: # virsh restore testRes.dat error: Failed to restore domain from testRes.dat error: operation failed: failed to start VM

Hi, I'm running into some problems with libvirt and hoping someone can point me at some instructions or maybe even help me out. First, are there any requirements on qemu version in order to use the "numatune" and/or "cpu/numa/cell" elements? Or do they use cgroups and not the native qemu numa support? Second, are there any instructions on how to set up cgroups? I

Hi, I am using guestfish to write some files into guest file system of my KVM domain. As you know, I have to mount guest disk at a position in the filesystem before I write any files into it , e.g.: mount /dev/VolGroup00/LogVol00 / But the problem is how I can get guest filesystem info without login guest. Now I have to power on the KVM domain, login the guest, remember which

I have fedora14 installed with standard libvirt-0.8.3. I can start VM using .xml files and also run: virsh schedinfo. the cgroup CPU controller is mounted and active . In fact I have the path to the Virtual machine : /dev/cgroup/cpu/libvirt/qemu/<vm name > Now I upgraded to libvirt-0.8.8 from a tar ball ( configure , make , make install) . I rebooted , new libvirtd started . virsh

Hi all, I have a RHEL5-update 3 x86_64 system, and I installed Samba 3.2.14-40 (from http://ftp.sernet.com/pub/samba/tested/rhel/5/x86_64/ ). I'm using OpenLDAP ( 2.3.43-3.el5 ,comes with RHEL5u3) as backend for winbind+samba in my PDC. With samba-3.0.33 that comes with RHEL5u3, i dont get that "eventlogadm" works how explain in http://wiki.samba.org/index.php/Event_Logging: For

libguestfs usually needs qemu. However it only requires an emulator for the same architecture, not for all architectures. libvirt-daemon-kvm pulls in qemu which pulls in emulators for all architectures, as well as a bunch of other stuff we don't need at all like network interface support and nwfilter. There are no Fedora TCG-only arches, so drop the conditional section. I also made support

Hi, I tired to add second AD domain to provide access to my samba share from RHEL5u3 server. Share access is working for primary domain and still users from second domain doesn't have access to shares. wbinfo -u shows user details from both domain. I could see below errors popped up in logs. Updated krb5.conf with both domians realms. do we need to update any additional steps in smb.conf for

Hey everyone, Can anyone explain the scedinfo parameters? I am wondering if I can use this, (along with host side niceness scheduler tweaks) to cause vCPUs to dominate the total time of the CPUs they are pinned to. Here are the sched info parameters: Scheduler : posix cpu_shares : 0 vcpu_period : 0 vcpu_quota : 0 emulator_period: 0 emulator_quota : 0 The documentation (

I resolved topic 1 please diregard ( libvirtd.conf : Authentication / auth_tcp="none") .
