[libvirt-users] No driver found during virt-install / kickstart
by Joe Linoff
Hi Folks:
I am getting a "No driver found" dialogue when I try to build a guest
using virt-install using a kickstart file. I am stuck. I am not sure how
to fix or even debug this problem.
Can anyone suggest a way forward?

[libvirt-users] Failed to bind socket to '/var/run/libvirt/libvirt-sock': Permission denied
by 何鑫
Hi all, When I start self-built libvirtd by "libvirtd -d -l -f libvirtd.conf", it shows that error : virNetSocketNewListenUNIX:346 : Failed to bind socket to '/var/run/libvirt/libvirt-sock': Permission denied I have removed some requested comments in libvirtd.conf. The key settings are shown as below: listen_tcp = 1 tcp_port = "16509" listen_addr = "0.0.0.0" unix_sock_group = "root" unix_sock_rw_perms = "0770" unix_sock_ro_perms = "0777" unix_sock_dir = "/var/run/libvirt" Is there any thing wrong? Need I start libvirtd by root?
Thanks a lot!
Best Regards!Corey

[libvirt-users] re-create disk image file
by Joe Linoff
Hi Everybody:
I am curious about how to re-create a disk image file from a running
guest when the original disk image file is accidentally deleted. This
came up recently during a test scenario but I couldn't figure out how to
do it.
Thanks,

[libvirt-users] CPU Mode= Host passthrough
by Michael Beham
Hi,
I´m doing some research on Nested Virtualization with KVM and Xen. My
cpu on bare-metal system is a Opteron_G4 --> (AMD Opteron 4280).
qemu-version 1.0; libvirt 0.9.12
For nesting KVM in KVM I´m adding the <cpu mode='host-passthrough'/>
command to the XML-File of the VM on Layer 0. So I´m able to install KVM
in KVM and create nested guests at Layer 2.
L2 --> Nested VM
L1 --> KVM / XEN
L0 --> KVM
If i try the same with installing Xen in the VM on Layer 1 Xen don´t
boot and I get following error:
Panic on CPU 0:
GENERAL PROTECTION FAULT
[error_code=0000]
If I remove <cpu mode='host-passthrough'/> command from the VM´s XML Xen
boot is successful and Nesting Xen in KVM works!
May this problem depends on the following problem -->

[libvirt-users] virsh vol-create-as failing on NFS automount for chmod (dynamic_ownership = 0)
by Joe Linoff
Hi Everyone:
I am trying to create a volume using the vol-create-as command but it
fails with an "Operation not permitted" error. It appears to be caused
by an attempt to run chown on an NFS mounted file system but I have set
dynamic_ownership to 0 in /etc/qemu.conf.
Is it possible to disable the chown operation? If not, is there a guide
that describes how to create storage pools on NFS filers? I have read
http://libvirt.org/storage.html but there was no discussion of to work
around this problem.
Any help would be greatly appreciated.
Here is the command and error message:
$ virsh vol-create-as default webtst 10G
error: Failed to create vol webtst
error: cannot create path '/var/lib/libvirt/images/webtst': Operation
not permitted
The /var/lib/libvirt/images is linked to a common filer:
/shared/vm/images. The permissions on the directory are 0777.
When I looked at tail /var/log/libvirt/libvirtd.log it showed that the
problem was occurring because a chown command:

[libvirt-users] hotplug
by Douglas Russell
Another separate thread for a slightly separate issue.
For some reason, hotplugging disks does not work for me.
I built my guest with ubuntu's vmbuilder. It's Precise, virtual.
I have acpiphp in my /etc/modules file:
$ lsmod
Module Size Used by
psmouse 97443 0
serio_raw 13211 0
virtio_balloon 13108 0
acpiphp 24231 0
floppy 70365 0
hotplug_pci seems to be compiled into the kernel:
$ grep HOTPLUG_PCI /boot/config-3.2.0-32-virtual
CONFIG_HOTPLUG_PCI_PCIE=y
CONFIG_HOTPLUG_PCI=y
CONFIG_HOTPLUG_PCI_FAKE=m
CONFIG_HOTPLUG_PCI_ACPI=m
CONFIG_HOTPLUG_PCI_ACPI_IBM=m
CONFIG_HOTPLUG_PCI_CPCI=y
CONFIG_HOTPLUG_PCI_CPCI_ZT5550=m
CONFIG_HOTPLUG_PCI_CPCI_GENERIC=m
CONFIG_HOTPLUG_PCI_SHPC=m
But when I attach a disk, absolutely nothing happens in the guest. No
messages in the logs, no change to /proc/partitions, no new device nodes.
When I reboot, the disk appears.
Any ideas?
Thanks,
Douglas
