[libvirt-users] error when call migrate function "error: invalid argument: qemuDomainMigratePrepare3: unsupported flags (0x200)"
10:02 a.m.
Hello,
I try to migrate a VM and I get this error :
loic@loic-VirtualBox:~/workspace/src/build/bin$ ./virsh --connect qemu:///system migrate
--live vmUbuntuPartage2CacheWriteBack qemu+ssh://192.168.10x.2x/system --unsafe
loic(a)192.168.10x.2x's password:
error: invalid argument: qemuDomainMigratePrepare3: unsupported flags (0x200)
Does somebody know this error?
I am working on windows 7, I have:
1) Virtual box with two vms ubuntu desktop 12.04: "VM1" and
"VM40"
2) One shared hard drive build with virtual box: "newDiskSharedFev.vdi"
In my VM1:
1) I have build one "vmUbuntuPartage" ubuntu server 12.10 on shared disk
with this command:
sudo virt-install -n vmUbuntuPartage -r 1500 --disk
path=/media/partage/newDiskSharedFev.vdi,bus=virtio,size=4,cache=writeback -c
/home/loic/Downloads/ubuntu-12.04.1-server-i386.iso --network network=default,model=virtio
--connect=qemu:///system --vnc -v
2) I have download and built libvirt-0.10.0 (I can give configure command if
necessary)
In my VM40:
1) I install libvirt with apt-get
2) I have mounted shared folder with "newDiskSharedFev.vdi"
So, in my VM1 I try to migrate my "vmUbuntuPartage" from VM1 to VM40 and I get
error above.
Here my configuration file /etc/libvirt/qemu/ vmUbuntuPartage.xml
-->
I try to change <driver name='qemu' type='raw' cache='none or
writeback or writetrough'/>

That means you libvirt doesn't support VIR_MIGRATE_UNSAFE flag. You have
to drop --unsafe from virsh migrate command to be able to migrate. Or
just upgrade to 0.9.11+.

Hello,
I am using latest version of libvirt: 0.10.0
If I drop unsafe flag I get "error: Unsafe migration: Migration may lead to data
corruption if disks use cache != none"
"cache=none": I try also to create a VM using virt-install with "-disk
...,cache=none" but I always get error "could not open disk image
/media/shared/dd.vdi", "could not open disk image
/media/shared/dd.qcow"...

On both sides?

Right. We want to bypass system and qemu cache during migration.
Unfortunately, we can't change cache once domain is started.
"cache=none": I try also to create a VM using virt-install with "-disk
...,cache=none" but I always get error "could not open disk image
/media/shared/dd.vdi", "could not open disk image /media/shared/dd.qcow"...
Well, this is unusual error message. I suspect qemu as the origin.
However, without libvirtd logs I am unable to tell.

Hello,
Good question:
- 0.10.0 build
- 0.9.3 on other side (with apt-get).
So I download and build 0.10.0 on other side and I don't have "error: Unsafe
migration: Migration may lead to data corruption if disks use cache != none"
anymore.
I get now another "error: XML error: missing security model when using multiple
labels"
Thanks for help,

This looks like a bug in the code that added support for multiple
security labels. We had several bugs there in the past and they should
already be fixed. Try to use newer libvirt (0.10.0 is quite old). You
may also try one of our maintenance releases, where we try to fix bugs
present in a particular libvirt release without implementing new
features.

Hello,
Thanks for answer,
So I try with 1.0.0 and 1.0.2 but I get same message:
"error: XML error: missing security model when using multiple labels"
Is it possible in configuration to disable security label, or to change value in order to
make other tests?
Maybe my .configure should use an option...I just use --prefix=/usr --localstatedir=/var
sysconfdir=/etc
I also change virtualBox with vmware (because cpuinfo flag vmx was not present, and kvm-ok
was not good).

Do you have 'auth_unix_rw="polkit"' set in /etc/libvirt/libvirtd.conf
(on dst, but check src as well)? You should either install & configure
polkit or switch to something you already have up & running (sasl, none).

Yes I forget to change my libvirtd.conf, I uncomment these lines:
unix_sock_group = "libvirtd"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"
and this one because I get "error: internal error Attempt to migrate guest to the
same host"
host_uuid = "6452c8fe-297b-4be7-8a48-9457ad32b62e" (output of the
'uuidgen' differents on both host)
These changes are made on both host, and are reboot: I still get
loic@ubuntu:~$ virsh --connect qemu:///system migrate --live ubuntuShared5
qemu+ssh://192.168.X.X/system --unsafe
loic(a)192.168.X.X's password:
error: internal error Attempt to migrate guest to the same host ubuntu
Strange because uuid are differents:
loic@ubuntu:~$ sudo dmidecode -s system-uuid
564DD52D-5B13-D29E-5587-21698DE7C788
loic@ubuntu:~$ sudo dmidecode -s system-uuid
564DCBD3-022C-8EAF-C1BC-943BB22EE9B5
loic@ubuntu:~$ virsh capabilities | grep uuid
<uuid>c77e0086-6108-0160-c543-a460de7f68a0</uuid>
loic@ubuntu:~$ virsh capabilities | grep uuid
<uuid>8aa7c641-711c-82c1-a60e-4d8d424b0555</uuid>
And to reply for a previous question:
loic@ubuntu:~$ virsh --connect qemu:///system --version
1.0.2

Hello,
Forget my previous mail, I reboot my VM and I get now answer for "virsh dumpxml

Authorization requires authentication but no agent is available.
Do you have 'auth_unix_rw="polkit"' set in /etc/libvirt/libvirtd.conf
(on dst, but check src as well)? You should either install & configure
polkit or switch to something you already have up & running (sasl, none).

The hostname for both hosts is "ubuntu", which is why it fails. You
should assign distinct hostnames to both hosts. And ideally, both
hostnames should be resolvable from both hosts and lead to the
corresponding IP address. See
http://wiki.libvirt.org/page/Migration_fails_with_%22Unable_to_resolve_ad...
And to reply for a previous question:
loic@ubuntu:~$ virsh --connect qemu:///system --version
1.0.2
Michal asked for "version" command rather than "--version".

Success!!!
I change hostname of my target (sudo hostname ubuntu40)
And I modify my command as in link above.
-->
virsh --connect qemu:///system migrate --live ubuntuShared5 qemu+ssh://192.168.X.X/system
tcp://192.168.X.X--unsafe --verbose
loic(a)192.168.X.X's password:
Migration: [100 %]
And on target VM, I see migrated vm:
loic@ubuntu:~$ virsh --connect qemu:///system list
Id Name State
----------------------------------------------------
2 ubuntuShared5 running
Thanks a lot for help,
I hope this topic will help others!
I use libvirt-1.0.2.
