[libvirt-users] ceph rbd pool and libvirt manageability (virt-install)
by Jelle de Jong
-----BEGIN PGP SIGNED MESSAGE-----
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] [RFC] per-device metadata
by Francesco Romani
Hi,
Currently libvirt supports metadata in the domain XML. This is very
convenient for data related to the VM, but it is a little awkward for
devices. Let's pretend I want to have extradata (say, a specific port
for a virtual switch) related to a device (say, a NIC). Nowadays I can
store that data in the metadata section, but I need some kind of mapping
to correlate this piece of information to the specific device.
I can use the device alias, but this is not available when the device is
created. This is also more complex when doing hotplug/hotunplug, because
I need to do update device and update metadata; if either fails, the
entire operation must be considered failed.
It would be nice to be able to attach metadata to the device, and this
is what I'm asking for/proposing in this mail.
Would it be possible in a future libvirt release?
If this is not possible, what's the best way to do the aforementioned
mapping? If it's alias (or device address), how can I be sure than I'm
addressing (no pun intended) the right device when I don't have them?
(e.g. hotplug new device, or just first time VM created)?
Thanks,

[libvirt-users] Bluetooth Device Support
by Max Ehrlich
Hi,
I want to create a virtual hci device on my virtual machine. I have seen
that qemu has options supporting this
https://qemu.weilnetz.de/doc/qemu-doc.html#Bluetooth_0028R_0029-options
and
https://qemu.weilnetz.de/doc/qemu-doc.html#pcsys_005fusb
Is there any support for these options in libvirt? I was not able to find
anything in documentation so I added the qemu command line xml as follows
<qemu:commandline>
<qemu:arg value='-usbdevice'/>
<qemu:arg value='bt:hci'/>
<qemu:arg value='-bt'/>
<qemu:arg value='hci,host'/>
</qemu:commandline>
but when I try to run my machine from virt-manager i get the following
error:
Error starting domain: internal error: process exited while connecting to
monitor: 2017-02-28T21:25:51.735987Z qemu-system-x86_64: -device
ich9-usb-ehci1,id=usb,bus=pcie.0,addr=0x1d.0x7: PCI: slot 29 function 7 not
available for ich9-usb-ehci1, in use by ich9-usb-ehci1
this error does not appear if I remove the commandline xml nodes
Does anyone have any guidance for troubleshooting this?
If it helps at all, virsh -v gives 2.1.0, virt-manager about page lists
1.3.2 and qemu-system-x86_64 --help gives 2.6.1 I am running Ubuntu 16.10.

Hi,
With a non-root user account, I am launching virtual machines and would like to get CPU stats for each Core (using python API or not) but face the following problem:

[libvirt-users] shutdown -r now hangs in qemu-/kvm-vm
by Dan Johansson
Since updating app-emulation/libvirt and/or app-emulation/qemu (both
were updated at the same time) I have a problem executing "shutdown -r
now" in the vm ("shutdown -h now" works fine).
When I execute "shutdown -r now" in the vm the shutdown process runs
perfect until "Remounting root-filesystem readonly" and than it hangs
and I have to "Force Power Off" to reboot.
Any suggestion what could be wrong and what I can do to solve it?

[libvirt-users] error : Failed to switch root mount into slave mode: Permission denied
by Kyle Peterson
libvirt-3.0.0
When attemping to create a virtual machine I receive the error "error : Failed to switch root mount into slave mode: Permission denied”.
I’m attempting to run qemu/libvirt/virt-manager in an Arch Linux lxc container on a Ubuntu 16.04 host. The host uses zfs for its containers. The arch container is set up as a priveleged container. I do already have kvm/qemu/libvirt working in a Ubuntu container. The reason for the arch container is because I want to try a newer version of qemu/libvirt.
I’m not finding anything on google about this error message. Any way to get around it?

[libvirt-users] "virsh list" hangs
by Yunchih Chen
`virsh list` hangs on my server that hosts a bunch of VMs.
This might be due to the Debian upgrade I did on Feb 15, which upgrades
`libvirt` from 2.4.0-1 to 3.0.0-2.
I have tried restarting libvirtd for a few times, without luck.
Attached below are some relevant logs; let me know if you need some more
for debugging.
Thanks for your help!!

[libvirt-users] Determining domain job kind from job stats?
by Milan Zamazal
Hi, is there a reliable way to find out to what kind of job does the
information returned from virDomainGetJobStats or provided in
VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event callback belong to?
I'm specifically interested in distinguishing host-to-host migration
jobs (e.g. those started by virDomainMigrateToUri* functions) from other
jobs. If there is no better way, I'm thinking about examining presence
or values of certain fields in the stats. I'd be fine with that as long
as I can be sure it's a reliable way to identify the job kind.
Thanks,
Milan

[libvirt-users] Virsh command hanging
by abhishek jain
Hi,
I started the VMs with libvirt 3 days ago (17th Feb). Now when I am trying to shutdown the domain, all my virsh command is hanging even virt-manager remains in "connecting.." mode and is not showing active domains.When I set the libvirt debug env and call "virsh list" it hangs in poll. Here is the logsetenv LIBVIRT_DEBUG 1 virsh list
