I use lsmod | grep kvm, it shows kvm and kvm_intel. It shows:
kvm_intel 39608 0
kvm 247190 1 kvm_intel
BTW, I use virt-manager to create a new virtual machine for qemu/kvm, it
shows no guests are supported for this connection.
I tend to restart the service for libvirtd, service libvirtd restart, it
shows the error:
libvirtd: unrecognized service
libvirtd is in the directory: /usr/sbin/libvirtd

[libvirt-users] The error for creating a new vm for kvm
by Qian Feng
I checked the capabilities. I do not know why the guest is only for vbox.
<guest>
<os_type>hvm</os_type>
<arch name='i686'>
<wordsize>32</wordsize>
<domain type='vbox'>
</domain>
</arch>
</guest>
I want it run qemu-kvm. and when i run virsh define
/etc/libvirt/qemu/demo.xml. It shows error: Failed to define domain from
/etc/libvirt/qemu/demo.xml
error: unknown OS type hvm
Then I use virsh-install --prompt to install kvm guest, it shows error:
libvirtError: this function is not supported by the connection driver:
virConnectNumOfDefinedStoragePools
I really do not know how to do, please help me, thanks.

Please check if kvm and kvm_intel ( for systems with 'vmx' flag) / kvm_amd
(systems with 'svm' flag) are loaded in the system.

[libvirt-users] Strange connectivity issues with bridged networking and masquerade
by Kolja Scheffler
Hi all,
I'm currently in the process of building a 2-Node libvirt/KVM Cluster
and ran into some issues regarding the network connectivity of our
virtual machines.
Our setup seemed to work fine, we were able to browse to Google and our
own company website and some others from within the VM. Then we tried
microsoft.com to download some Windows iso images from MS Partner
Network. The page started to load, but only a few elements became
visible - then it sticked to: "Loading data from
microsoft.com" ...forever. A few other examples that do not work are:
* www.opera.com
* www.amazon.com
* www.speedtest.net
All of these pages load without any problem, when I access them from my
laptop or even with Firefox via X-Forwarding launched directly on the
hypervisor system. From within the VMs they just refuse to finish
loading. The only thing those pages have in common, as far as I can see,
is that they heavily utilize CDNs like Amazon Cloudfront or Akamai.
The idea behind our setup is, that all virtual machines communicate on
the 192.168.3.0/24 network. The nodes have a VLAN connection on eth1. To
allow connections between VMs on different hosts, we created the bridge
device br1 with eth1 attached and added the VMs to it. eth0 provides
internet access with xx.xx.220.0 as additional public failover ip.
We added 192.168.3.254 as additional IP to one of the node's br1 device
to use it as the default gateway for the VMs. This IP can be migrated
between the nodes.
Our setup looks like this:
____________
/ \
( Internet )
\____________/
/ \
Node1: | | Node2:
| |
xx.xx.217.8 (eth0) (eth0) xx.xx.217.10
xx.xx.220.0 \
{Masq.}
/
(eth1)----(eth1)
| |
192.168.3.1 [br1 ] [br1 ] 192.168.3.2
192.168.3.254 | |
| |
192.168.3.50 (vnet0) (vnet0) 192.168.3.75
----------
iptables looks like this:
root@vm01:~# iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A FORWARD -d 192.168.3.0/24 -o br1 -m state --state
RELATED,ESTABLISHED
-j ACCEPT
-A FORWARD -s 192.168.3.0/24 -i br1 -j ACCEPT
-A FORWARD -i br1 -o br1 -j ACCEPT
-A FORWARD -i eth0 -o eth0 -j ACCEPT
root@vm01:~# iptables -S -t nat
-P PREROUTING ACCEPT
-P INPUT ACCEPT
-P OUTPUT ACCEPT
-P POSTROUTING ACCEPT
-A POSTROUTING -s 192.168.3.0/24 ! -d 192.168.3.0/24 -j MASQUERADE
-A POSTROUTING ! -s 192.168.3.0/24 -d 192.168.3.0/24 -j MASQUERADE
---------
Some additional information that might be helpful:
root@vm01:~# virsh version
Compiled against library: libvir 0.9.12
Using library: libvir 0.9.12
Using API: QEMU 0.9.12
Running hypervisor: QEMU 1.1.2
---------
root@vm01:~# uname -a
Linux vm01.cluster 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64
GNU/Linux
---------
I don't know if it's really libvirt-related but perhaps someone here has
an idea what to try. Any advice on this is really appreciated, as I am
at my wits' end. Thank you in advance... :)
Kind regards

[libvirt-users] Information needed regarding the libvirt version libvirt-1.0.6-1
by arun abhinay
Hi,
We have upgraded the libvirt version from libvirt-1.0.5 to libvirt-1.0.6-1
on our linux machine. After this upgrade "virsh cpu-stats <domain>" command
is not working on our HardWare.
*virsh # cpu-stats test
error: Failed to retrieve CPU statistics for domain 'test'
error: internal error error accessing cgroup cpuacct for vcpu*
**
*# cat /proc/cgroups
#subsys_name hierarchy num_cgroups enabled
cpuset 3 4 1
ns 0 1 1
cpu 1 6 1
cpuacct 7 3 1
memory 2 3 1
freezer 0 1 1
net_cls 0 1 1
blkio 0 1 1
*
*# chkconfig --list | grep cg
cgroups_mount 0:off 1:on 2:on 3:on 4:on 5:on 6:off*
We have also found that there is no "cgroup" directory created by
kenel under "/sys/fs/". We suspect that the 'cgroup' controllers are not
mounted properly and hence the issue is observed. While using the
libvirt-1.0.5 version below mentioned mount commands were sufficient to
mount cgroup controllers
*mkdir -p /dev/cgroup_cpuacct
mount -t cgroup -o cpuacct cpuacct /dev/cgroup_cpuacct*
As cgroups hieracrhy inside libvirtd has changed in libvirt-1.0.6-1, we
feel that the above commands are now not sufficient. We feel we have to do
some more steps get the 'cgroups' mounted properly on our hardware.
Since we are new to libvirt and can you please help us by providing some
pointers to fix the above issue and get cpu-stats working on our HardWare.
Since we have to fix this on top priority, can you please reply as soon as
possible. Please let us know if you need any further information from our
side.
Thanks in advance.

[libvirt-users] the error for define the xml
by Qian Feng
Hi, everyone, I have already install libvirt. I want to use it on qemu. I
have set up qemu too. I do not know how to let libvirt manage the vms for
qemu. What i did ist that:
1) create the xml under /etc/libvirt/qemu/demo.xml
2) # virsh define /etc/libvirt/qemu/demo.xml
There is error as following:
error: Failed to define domain from /etc/libvirt/qemu/demo.xml
