[libvirt-users] Help!
by huachao yao
Buddy, I am a noob in libvirt develop.
When I want to create a domain by using virDomainDefineXML and displays a
window on the host desktop. But when I add the line
" <graphics type='sdl' display=':0.0'/>" into the config xml file, the
error as below will happen.
libvir: QEMU error : internal error process exited while connecting to
monitor: Could not initialize SDL(No available video device) - exiting
when I delete " <graphics type='sdl' display=':0.0'/>",I can create the
domain normally. Who can help me?!
The config xml file is as below:
<domain type='qemu'>
<name>qemu_ubuntu_01</name>
<memory>219200</memory>
<currentMemory>219200</currentMemory>
<vcpu>2</vcpu>

Also how do I get the System info(Like system tot memory use/Disk info/cpu info,network info etc through libvirt. Are there any palns to support this in the future release?
Also, how to I add a new API to libvirt?

[libvirt-users] Reg: Workaround to use pivot_root while using "rootfs" for "/" ?
by Alphonse Hansel Anthony
Hi All,
I am trying to start a lxc container using libvirt and I am facing an
issue due to pivot_root.
The return code from the system call “pivot_root” is EINVAL (Invalid
arguments).
I isolated the issue to this specific condition check within the system
call.
This is an code snippet from fs/namespace.c::pivot_root
* error = -EINVAL;
if (root.mnt->mnt_root != root.dentry)
goto out2; /* not a mountpoint */
if (root.mnt->mnt_parent == root.mnt) << this represents a circular
mount reference
goto out2; /* not attached */
if (new.mnt->mnt_root != new.dentry)
goto out2; /* not a mountpoint */
if (new.mnt->mnt_parent == new.mnt)
goto out2; /* not attached */
*
This issue occurs for me, since I am using fstype "rootfs" as "/" and all
binaries are mounted ISO's for execution within "/".
Based on information from the below links, I have realized, that pivot_root
is not possible for the above case.*
**https://lkml.org/lkml/2005/10/8/17
https://bugzilla.kernel.org/show_bug.cgi?id=4857
*
I would like to know , if my observations are correct and is there any
workaround to overcome this issue?
Any help in this regard would be useful.

[libvirt-users] (no subject)
by lingjiao.lc
Hi,
I’ve used the libvirt and sheepdog, they are so great!
But I have one question about libvirt and sheepdog.
As we know, I can use this command to create a sheepdog image,
#qemu-img create –f raw sheepdog:fedora15.img 40G
but how can I create a pool and volume for sheepdog with the xml of libvirt ?

[libvirt-users] libvirt ruby binding with vmware
by Ohad Levy
Hi,
I've been trying to use the ruby libvirt binding with vmware esx on F15,
however it doesnt seems to work, I get:
Libvirt::ConnectionError: Call to virConnectOpen failed: Cannot access CA
certificate '/etc/pki/CA/cacert.pem': No such file or directory
I've using the same uri with virsh and it works.
it seems like somehow the no_verify is not passed, or we are back to old
libvirt error messages :)
any idea?
thanks,
Ohad

[libvirt-users] pool-refresh on iSCSI pools does not actually rescan the bus
by Guido Winkelmann
Hi,
When I add a new LUN on an iscsi target and then issue a pool-refresh command
on the respective storage pool in libvirt, libvirt will not find the new lun
(or notice if luns have been removed).
I'm using a Dell PowerVault MD3200i iSCSI Array to hold the volumes for
virtual servers in libvirt. In libvirt, I have defined the storage pool as
this:
<pool type='iscsi'>
<name>iscsi01</name>
<uuid>52eb9c59-a7ac-a4e8-a26e-7ca112f0dd70</uuid>
<capacity>85899345920</capacity>
<allocation>85899345920</allocation>
<available>0</available>
<source>
<host name='10.3.1.15'/>
<device
path='iqn.1984-05.com.dell:powervault.md3200i.6782bcb0000859f3000000004d3eec7d'/>
</source>
<target>
<path>/dev/disk/by-id</path>
<permissions>
<mode>0700</mode>
<owner>-1</owner>
<group>-1</group>
</permissions>
</target>
</pool>
If I add a new LUN on the iSCSI array, and then issue the command "pool-
refresh iscsi01", followed by "vol-list iscsi01" in virsh, the list does not
contain the new volume. The only workaround I have found so far for this is to
manually log in to the host server as root, do "iscsiadm -m discovery -t
sendtargets -p 10.3.1.15" and then issue the pool-refresh command in libvirt.
Libvirt is libvirt-0.8.3-4.fc14.x86_64 on Fedora 14.
Is this supposed to work like this? If not, will a newer version fix that
problem?
Regards,
Guido

[libvirt-users] Strange libvirt exit status 1 (LXC containers)
by Stephen Eilert
Hello,
I've encountered the following error, trying to start a domain:
error: internal error Child process (PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin LIBVIRT_DEBUG=2 LIBVIRT_LOG_OUTPUTS=2:syslog:libvirtd /usr/libexec/libvirt_lxc --name vm_14 --console 18 --handshake 21 --background --veth veth1) status unexpected: exit status 1
I see nothing relevant in syslog, google searches have returned nothing. Starting libvirt_lxc manually seems to work (the process never returns), but of course the VMs do not start.
I am at a loss on what to do next. I'm running Ubuntu 10.04, which is itself a guest system running under virtual box (host is OSX Lion). I've compiled libvirt from git (using /usr as the --prefix, after removing the OS package), LXC containers are installed from a PPA, as the default Ubuntu kernel doesn't enable network namespaces. LXC itself doesn't appear to be a problem, as I can start VMs with lxc-start. Since I required libvirt's API, using LXC directly is not desirable.
Does anyone have any tips on what I should be looking for? Thanks.

[libvirt-users] Problem to migrate virtual machine between two hosts with same uuid
by info＠umbertocarrara.it
hi at all,
i'm trying to migrate a vm between two host but fails, this is what
I did:
virsh # start win2008
Domain win2008 started
virsh # list
Id Name State
----------------------------------
1 win2008 running
virsh # migrate --live win2008 qemu+ssh://host2/system
error: internal error Attempt to migrate guest to the same host
00010203-0405-0607-0809-0a0b0c0d0e0f
if I type on both hosts:
host1
virsh # sysinfo
.......
<system>
<entry name='manufacturer'>Supermicro</entry>
<entry name='product'>X9SCL/X9SCM</entry>
<entry name='version'>0123456789</entry>
<entry name='serial'>0123456789</entry>
<entry name='uuid'>00010203-0405-0607-0809-0A0B0C0D0E0F</entry>
<entry name='sku'>To be filled by O.E.M.</entry>
<entry name='family'>To be filled by O.E.M.</entry>
</system>
........
host2
virsh # sysinfo
.......
<system>
<entry name='manufacturer'>Supermicro</entry>
<entry name='product'>X9SCL/X9SCM</entry>
<entry name='version'>0123456789</entry>
<entry name='serial'>0123456789</entry>
<entry name='uuid'>00010203-0405-0607-0809-0A0B0C0D0E0F</entry>
<entry name='sku'>To be filled by O.E.M.</entry>
<entry name='family'>To be filled by O.E.M.</entry>
</system>
........
The problem seems to be the same uuid on both hosts,
1) is correct?
2) if is correct, how I can resolve?
Thanks a lot in advance
Umberto
