[libvirt-users] ceph rbd pool and libvirt manageability (virt-install)
by Jelle de Jong

Hash: SHA1
Hello everybody,
I created a rbd pool and activated it, but I can't seem to create
volumes in it with virsh or virt-install?
# virsh pool-dumpxml myrbdpool
<pool type='rbd'>
<name>myrbdpool</name>
<uuid>2d786f7a-2df3-4d79-ae60-1535bcf1c6b5</uuid>
<capacity unit='bytes'>6997998301184</capacity>
<allocation unit='bytes'>10309227031</allocation>
<available unit='bytes'>6977204658176</available>
<source>
<host name='ceph01.powercraft.nl' port='6789'/>
<host name='ceph02.powercraft.nl' port='6789'/>
<host name='ceph03.powercraft.nl' port='6789'/>
<name>libvirt-pool</name>
<auth type='ceph' username='libvirt'>
<secret uuid='029a334e-ed57-4293-bb99-ffafa8867122'/>
</auth>
</source>
</pool>
# virt-install --version
1.0.1
# virsh --version
1.2.9
I ended using virsh edit ceph-test.powercraft.nl and making creating
the disk manually.
<disk type='network' device='disk'>
<auth username='libvirt'>
<secret type='ceph' uuid='029a334e-ed57-4293-bb99-ffafa8867122'/>
</auth>
<source protocol='rbd' name='libvirt-pool/kvm01-storage'>
<host name='ceph01.powercraft.nl' port='6789'/>
<host name='ceph02.powercraft.nl' port='6789'/>
<host name='ceph03.powercraft.nl' port='6789'/>
</source>
<target dev='vdc' bus='virtio'/>
</disk>
I use virt-install a lot to define, import and undefine domains, how
can I use virt-install to manage my rdb disks?
Kind regards,
Jelle de Jong

[libvirt-users] virRandomBits - not very random
by Brian Rak
I just ran into an issue where I had about 30 guests get duplicate mac
addresses assigned. These were scattered across 30 different machines.
Some debugging revealed that:
1) All the host machines were restarted within a couple seconds of each
other
2) All the host machines had fairly similar libvirtd pids (within ~100
PIDs of each other)
3) Libvirt seeds the RNG using 'time(NULL) ^ getpid()'
This perfectly explains why I saw so many duplicate mac addresses.
Why is the RNG seed such a predictable value? Surely there has to be a
better source of a random seed then the timestamp and the pid?
The PID seems to me to be a very bad source of any randomness. I just
ran a test across 60 of our hosts. 43 of them shared their PID with at
least one other machine.

[libvirt-users] stream finish throws exception via python API
by Shahar Havivi
Hi,
The following snippet works fine e.g. receiving the data but when calling
stream.finish() we get the following error:
stream = con.newStream()
vol.download(stream, 0, 0, 0)
buf = stream.recv(1024)
stream.finish()
libvirt: I/O Stream Utils error : internal error: I/O helper exited abnormally
Traceback (most recent call last):
File "./helpers/kvm2ovirt", line 149, in <module>
download_volume(vol, item[1], diskno, disksitems, pksize)
File "./helpers/kvm2ovirt", line 102, in download_volume
stream.finish()
File "/usr/lib64/python2.7/site-packages/libvirt.py", line 5501, in finish
if ret == -1: raise libvirtError ('virStreamFinish() failed')
libvirt.libvirtError: internal error: I/O helper exited abnormally
Am I doing something wrong?
Thank you,
Shahar.

[libvirt-users] systemctl libvirt-guests.service fails to start during host boot
by Benoit
Hi,
I have been using qemu and kvm for a while but I am newbie to libvirt.
(but I really like it :)
I am on Parabola (fork of Archlinux, using systemd)
I only got an issue regarding libvirt-guests service, when my host boots
about 7 times to 10 I got a issue on the service.
------------------------------------------------------------------------
systemctl status libvirt-guests.service
● libvirt-guests.service - Suspend Active Libvirt Guests

------------------------------------------------------------------------
it is like the service starts too early.
When I restart the service everything is good and if I shutdown it sends
the ACPI message correctly to my guests.
I already seen lot of discussion but not able to find any working
solution.. any idea to help me figure out the issue ?
many thanks

Hope you can help me submit the error.
Apologies for any inconvenience.

* Implement VIR_DOMAIN_QEMU_AGENT_COMMAND_SHUTDOWN
* Implement virDomainDefineXMLFlags
* Implement virDomainRename
* Implement virDomainSetUserPassword
* Implement VIR_DOMAIN_TIME_SYNC
* Fix the return value from virStreamSourceFunc so volume upload works
Version 0.7.0 is available from http://libvirt.org/ruby:
Tarball: http://libvirt.org/ruby/download/ruby-libvirt-0.7.0.tgz
Gem: http://libvirt.org/ruby/download/ruby-libvirt-0.7.0.gem
