答复: How could I do the guest mount operation from the host?
Hi,
I have tried usb and it doesn’t work. I don’t know if the filesystem tag could work…
I find in the formatdomain docs about the filesystem:
<filesystem type='mount' accessmode='passthrough'>
<driver type='path' wrpolicy='immediate'/>
<source dir='/export/to/guest'/>

Yes, my modification is like you. I doubt that if the mount operation on the host is reasonable…
And what is p9?

Hi,
Thanks for your response!
But when I use the ssh, I need to know the guest password, and actually it
belongs to network communication. I don’t know if the libvirt has some means just
like to control the domain to implement the operation?

Re: VM Performance using KVM Vs. VMware ESXi
Thanks Dominique & Daniel.
Looks like i need to upgrade my VMs kernel to make it aware of virtio.
Found this information from this link:
http://wiki.libvirt.org/page/Virtio#Disk_.28block.29_device_driver
I tried without upgrading the Kernel and as soon as i start my VM it got
into Kernel Panic. I will try using virtio after upgrading my VMs kernel.
Thanks for all the responses and

snapshot of running vm's
Hi,
i'd like to create snapshots of my running vm's. I have several hosts with
SLES11 SP4 64bit. I use libvirt 1.2.5-7.1 . VM's are Windows 7, SLES,
Ubuntu, Opensuse.
I use raw files for the vm's.
I try to orientate myself by
http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit .
The hosts are backuped every night by a network based backup solution
(Legato).

Re: Windows Server 2008 - KVM
Hi there!
I have installed a new VM with Win2k8 and the serial virtio driver works
fine. I don´t know why the other VM the BSOD happen!
About the performance, I had the impression that only one core is
used.....PID 8301 is a linux VM with 4 VCPU and 2 GB of RAM...

Re: Windows Server 2008 - KVM
Hi there!
Although the guest has 2GB memory, the windows guest was adjusted to
support this.
I guess that the LVM is the best choice! I will save all images to other
disk and re-build the partition with LVM. Do you recomend to use ext4 or
zfs ?
- About the apparmor, I have my doubts, I will try to disable and see what
will happen!
- About the tablet input device, I removed! Some forums say that

Re: Windows Server 2008 - KVM
Hi there!
I will do soon the disk config, but first I will do some labs.
I´m trying to install the virtio driver to comunicate using qemu-agent but
when the driver is installed, the BSOD happens (win2k8 R2).
I tried with virtio-drivers version 100, 110 and 117, both happens BSOD.
Do you has a tip ? :)
Thanks buddy!

Re: Windows Server 2008 - KVM
Hi Dominique,
You’ll have to convert the qcow to raw, create a LVM-volume (don’t create a
file system on the volume), and dd the raw tot he LVM volume…
Convert the qcow to raw, Ok
Create a LVM-Volume, OK
Don´t create a file system on the volume ?? Is not clear why...
DD the raw to the LVM? How ? I don´t understand this point....
Thanks a lot!

Re: libvirt 1.19: could not open drive file (permission denied)
@requillart
Don't get me wrong. It's no problem to use other partitions. Only, you have to add the location to the storage pool of libvirt...
Sorry, no experience with gnome-boxes.
@crequill
Add a new storage pool with the destination /home/crequill/VM
You can't fool apparmour with a link...
Also with adding the storage pool, it's easier to get a clear picture of the usage of your

Yeah, Dominique, your wiki was one of the many docs I read through

it. I'm an Arch user, and I couldn't find anything to indicate qemu, as its
compiled for Arch, will look in /etc/default/qemu-kvm. And now that I've

Re: Efficient live disk backup with active blockcommit : Failed 'block-commit': Could not reopen file: Permission denied
This is not a libvirt/redhat question…
With your method you can only revert to versions which are available in the standard repositories. You’ll have to download the packages manually to force a different version. Use with caution. There is a reason why the version isn’t in the standard repositories.

os x comes with openssh, and some other nixy goodness. the rest you

VM's in a HA-configuration - synchronising vm config files
Hi,
i'd like to establish a HA-Cluster with two nodes. My services will run inside vm's, the vm's are stored on a FC SAN, so every host has access to the vm's. But how can i keep the config files (xml-files under /etc/libvirt/qemu) synchronised ? Is there a possibility to store the config files somewhere else ? E.g. a partitition with ocfs2 on the SAN ?
If not, what would you do
