hi, virt guys, This is Hongqing from Fedroa QA team. I try to forward the guest installation logs to host with virtio. I have used virsh edit <guestName> to add a channel, it works fine. I think it would be better if I can initialize it when I create the guest using virt-install, and virt-install also offers the option, I have tried below, but it does not work. virt-install

Hi, Has anyone used libvirt to start/stop/manage LXC (linux containers) ? Is it supported at all? Last I tried, had few issues and the reply was : /// Note that libvirt lxc driver is a different implementation from lxc tools and doesn't use lxc tools internally. You may not be able to do what you are doing with lxc tools. Especially, the driver doesn't take aware of files and settings

I have febootstrap ported to and working on Arch, but there are a few packages missing from the main Arch repos, and the packages need to be in the main repos for the febootstrap sequence to work. So I have a few quick questions, first, how well does the supermin app work, without augeas, are zfs, gfs and hfs used only for mounting those filesystems inside the vm image, and I noticed that there is

I try to add some rules to filtering network, example <filterref filter='clean-traffic'/> or <filterref filter='no-ip-spoofing'/> and vm not starting with message virsh start freebsd8.2 error: Failed to start domain freebsd8.2 error: internal error IP parameter must be given since libvirt was not compiled with IP address learning support what do I do wrong?

I'm writing an app and using the Python bindings for libvirt. Everything is fine but, in some cases I need to call lookupByName(). There are a lot of times when the name will not exist, I trap the exception, however I still get this message printed to stderr: libvir: QEMU error : Domain not found: no domain with matching name 'foo' Is there any way to turn this off? This is a

Hello List, I run a few VMs via libvirt using '--sdl'. I would like to use qemu parameters -no-quit, -no-frame and -ctrl-grab with libvirt. Does libvirt support a way to use these qemu parameters? Does libvirt provide a way to add these options under <graphics/> in the domain.xml using 'virsh edit domain.xml'? My current <graphics/> is as follows: <graphics

Hello, We are using libvirt 0.8.3 to build KVM guests (KVM version is qemu-kvm 0.12.5). I see kvm supports aio flag with either native or threads option. Where in libvirt XML should we define aio option? Thanks in advance Ranga -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi , I have two KVM guests in ubuntu host machine.I am using Python binding of Libvirt API to query on the hypervisor and capture the CPU , memory related information of the guest machines. I need to capture the detail information regarding CPU like : cpu_aidle, cpu_idle, cpu_speed, cpu_wio and memory like :mem_cached,mem_buffers,mem_free etc. of the guest machines. How could I get these

Hi, Simple question that I can't track down any notable discussion about, let alone an answer... Is it possible to define what the "default" nic and storage types are? I am deploying images out of cobbler using koan and all of them are running virtio wherever applicable, but this is not the default, and at present there is no way within koan or cobbler to define what type of

My virtual machine xml file has <vcpu>2</vcpu> clause while the host has 2 physical cpus (cores). Is this enough to cause a VM running 2 endless loop threads to use the 2 cores ? In my case the VM running reports (cat /roc/cpuinfo) that it has 2 vcpus but it uses only 1 core (at a time) because the 'top' at the host shows 100%cpu (out of total 200%) used by the

Hallo everyone, in March 2010 there was a discussion[1] about live migration of LXC Containers using libvirt. I was just wondering if there are any updates to this? regards, Dan Luedtke [1] http://www.mail-archive.com/lxc-users at lists.sourceforge.net/msg00198.html -- https://www.danrl.de/ GPG Key ID: 0xF8504F3E

I would like to use the virDomainMigrateSetMaxDowntime but I'm a bit confused about how to use it. If I try to set the downtime before I call domain.migrate(), I get the error "domain is not being migrated". But I cannot call it afterwards because domain.migrate() does not return until the migration has completed. Am I meant to put the call to domain.migrate() into a separate

Hi, I'm trying to get a virtual serial device up and running between my host and virtual machine with a device name on the host. I'm using libvirt 0.8.3 and qemu 0.13.0. The challenge that I'm running into is that I'm able to get a serial device, but I cannot fix it to a pre- defined device name. For example, I'm using the following in my VM's xml file:

Hello, I am running libvirt 0.8.3 with a couple VMs using a LVM VG that I had previously setup on my host. I did not use the storage pool functionality of libvirt to create the VG in the first place ('pool-list' is empty). Now I want to be able to take snapshots of the VMs. Having read this previous post [1] on the mailing list, I gather that libvirt does indeed support taking snapshots

Hello: When I start the guest with an image on NFS file system, the ubuntu doesn't boot, It's remain on inittrams. I've tried to redefine the guest without <apic> <pae> configuration as I see on a blog, and I've increased the parameters of the mount to rsize=32768 and wsize=32768, but it still doesn't work. Can anyone give any advice to get it? Thank you very much.

Hello, Is there any way to change VNC password without rebooting virtual machine? It is available through qemu monitor, but, it seems, there is no way to do add monitor to kvm. -- Nikita A Menkovich http://libc6.org/ JID: menkovich at gmail.com

Hello all, As I've been exporing libvirt api, I've seen event registerers, and types of events are defined, undefined, and you know the rest. Is it all for event types? Any ideas about how to look for a device access event, for example? Kind regards -------------- next part -------------- An HTML attachment was scrubbed... URL:
