[libvirt-users] Does libvirt support xapi/xe toolstack?
by Guillaume Thouvenin 30 Sep '13

30 Sep '13

Hello, I installed the last version of Xen (xenserver-core-0.9.0-9.x86_64 from yum) and I'm trying to manage my VMs with virsh. The version that I installed is using the Xapi/xe toolstack. The problem I have is that I'm not seeing the VM that is started with "virsh -c xen:/// list --all". Here is what I have: root# xe vm-list uuid ( RO) : 022226ed-07be-37fc-5b52-f798320e2726 name-label ( RW): vm1 power-state ( RO): running uuid ( RO) : 394fa633-f600-45f9-bea7-3bf4a9fd06fd name-label ( RW): Control domain on host: unknown power-state ( RO): running root# virsh -c xen:/// list --all Id Name State ---------------------------------------------------- # According to [1] it seems that libvirt is using Xend daemon to communicate. The problem is that Xend is now deprecated since Xen 4.1. So am I wrong with this assumption or is there something to configure to be able to use libvirt with Xapi/XE toolstack? I looked in the documentation but I only found [2] but I didn't see any special settings... Regards, Guillaume [1] http://libvirt.org/architecture.html [2] http://libvirt.org/drvxen.html

Hello all, i am now running xen 4.2.3 on centos 6.4. As we know, the default libvirt package could not work well with xen on centos6.x. So, i compile the libvirt by my self, and i have compiled libvirt-1.1.1, libvirt-1.1.2, libvirt-1.1.3. After the installation of libvirt, i run virt-manager, but it print error as below. *ImportError: /usr/local/lib/libvirt.so.0: version `LIBVIRT_PRIVATE_0.10.2' not found (required by /usr/lib/python2.6/site-packages/libvirtmod.so)* I found one topic talk about the erorr, but get nothing https://www.centos.org/modules/newbb/viewtopic.php?topic_id=41893&forum=56 anyone meet the same error as me? any response is appreciated!

[libvirt-users] virNodeInfo returns MBytes instead of bytes
by Sam Giraffe 30 Sep '13

30 Sep '13

Hi, http://www.libvirt.org/html/libvirt-libvirt.html#virNodeInfo says that memory size is in kilobytes, however when I use this call I get an answer in Megabytes, see below. The hypervisor has 16 GB of RAM. $ python Python 2.6.6 (r266:84292, Jul 10 2013, 22:48:45) [GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>> conn=libvirt.open("qemu+ssh://xx@xx.xxx.com/system") Enter passphrase for key '/home/xx/.ssh/id_rsa': >>> hv_info=conn.getInfo() >>> hv_info ['x86_64', 15919, 8, 3292, 1, 1, 4, 2] 15,919 is the number I am referencing, should that not be in bytes and not MB? 8 is the number of cores, CPU is 3.2Ghz. $ rpm -q libvirt libvirt-0.10.2-18.el6_4.14.x86_64 $ uname -a Linux xx.xxx.com 2.6.32-358.18.1.el6.x86_64 #1 SMP Wed Aug 28 17:19:38 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Thanks

by yao xu 27 Sep '13

Hi Guys! Recently , I am searching way to run libvirt-python on windows , and using the python api just like in linux . But I found that ,libvirt-python can only run in cygwin environment . In windows environment , when I input "import libvirt" It indicates *ImportError: DLL load failed:* * * * it seemed something wrong when importing libvirtmod* * * * *the libvirt.py libvirtmod.pyd is compiled in *cygwin* environment * * But it doesnot show anything more. Is there anyone do this thing like me ? Anyone can provide any solution to use python-libvirt in a normal python programe. Thanks.

[libvirt-users] Strange results with QoS definition
by Patrick Herzfeld 27 Sep '13

27 Sep '13

Hi I'm currenty testing network QoS implementations stumbled upon quite strange results when using QoS definitions inside the virtdomain xml. I'm testing bandwidth from a virtdomain towards a hardware server connected to the same switch, both connected to gigabit ports. Iperf tells me the bandwidth is around 939 Mbit/s. I added this to my virtdomains xml: <bandwidth> <inbound average='1280'/> <outbound average='1280'/> </bandwidth> This should limit the bandwidth to around 10 megabit/s 1280 kilobytes/s, however i get only around 5.14 Mbits/sec... Has anyone an idea what causes this difference? I already checked the applied qdisc & class: root@testvirt-patrick:~ # tc qdisc sh dev vnet1 qdisc htb 1: root refcnt 2 r2q 10 default 1 direct_packets_stat 0 qdisc ingress ffff: parent ffff:fff1 ---------------- root@testvirt-patrick:~ # tc class sh dev vnet1 class htb 1:1 root prio 0 rate 10240Kbit ceil 10240Kbit burst 1598b cburst 1598b Freundliche Grüsse / kind regards Patrick Herzfeld -- Nine Internet Solutions AG, Albisriederstrasse 243a, CH-8047 Zuerich Tel +41 44 637 40 00 | Support +41 44 637 40 40 | Fax +41 44 637 40 01

[libvirt-users] virtio channel socket bind error
by Chunduru Venkata, Ravi 27 Sep '13

27 Sep '13

Hi All, My intent is to make virtio unix channel work. I could configure the XML and launch VM and could see the port in /dev/virtio-ports <channel type='unix'> <source mode='bind' path='/tmp/appl_port'/> <target type='virtio' name='appl_port'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> When I see on the host, the unix socket is already binded and is in listening state. echo "test this" > /tmp/appl_port bash: /tmp/appl_port: No such device or address netstat -nax | grep appl_port unix 2 [ ACC ] STREAM LISTENING 15302258 /tmp/appl_port 1) Can some one please have a look and help me fix this. 2) if I don't set source mode to 'bind', it gets set to 'connect' in xml and VM fails to boot up. I would like to understand the different types of source mode. Dmesg shows below denied message for connect mode. 84616.025345] type=1400 audit(1380129082.835:210): apparmor="DENIED" operation="capable" parent=1 profile="/usr/sbin/libvirtd" pid=9804 comm="libvirtd" pid=9804 comm="libvirtd" capability=29 capname="audit_write" Thanks, -Ravi.

[libvirt-users] connecting with the libvirt daemon on xen+debian
by Aamir A R 27 Sep '13

27 Sep '13

Hi all:Me being new to libvirt, this may sound very trivial to you. Any help is welcome. I have deb7u1, with xen4.1.4 and libvirt 0.9.12 (since those are the latest available thru apt utility) . I have enabled xen-unix-server as well as xen-http-server in the /etc/xen/xend-config.sxp file. But I still keep getting the following message. >From local: root@debian:~# virsh -c xen:///error: unable to connect to 'localhost:8000': Connection refusederror: failed to connect to the hypervisorroot@debian:~# >From remote: [root@CentOS-6 libvirt]# virsh -c xen+ssh://root@10.240.64.112/root@10.240.64.112's password: error: unable to connect to 'localhost:8000': Connection refusederror: failed to connect to the hypervisor[root@CentOS-6 libvirt]#
