[libvirt-users] RX dropped packets on guests subnets
by pichon
Hello,
I have first a question (and then may be a problem), that I have difficulties to understand and eventually to investigate.
On each of my guests VM, I see constantly a RX dropped number increasing , Even if the VM does nothing !
ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.100.15 netmask 255.255.255.0 broadcast 192.168.100.255

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 4 bytes 340 (340.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
(1) Is that a normal behaviour ?
(2) Could you give me some hints where/how to investigate
Here are a number of informations:
- The virsh LAN setup
- The VM XML description
- iptables-save on the hosts
- and then some packages version
Thanks in advance
Patrick
My setup is as follow:
An host running a Fedora 23 (minimal) and a VM guest running a Fedora 23
I have created 3 Networks ,
- 2 fully isolated ( mgt-private-lan and pre-private-lan)
- 1 Nat via the host NIC
Here after are the information related to the nat Network on which I have consistent increase of RX Dropped Packets

[libvirt-users] starting a domain only when you have enough resources
by Andrei Perietanu
Hi all,
I am running KVM on a 3.18 kernel. The system runs and Atom processor with
2Gb RAM.
Using KVM you obviously can over allocate your resources: say you have 4
guests each configured with 1GB ram. Running all four at the same time,
depending on the workload, can crash the system - I get a kernel trace when
this happens.
But let's consider a simpler case: one guest with 1.5 Gb RAM, ubuntu 14.03.
During the installation the system will again crash.
The memory statistics (top or proc/meminfo) will show that the FreeMemory
goes down to 12Mb when this happens - which kind of makes sense considering
the host will require some RAM to run.
But the question is: does libvirt offer any way to prevent this from
happening?
Some way of not allowing the user to start a guest unless you have enough
free memory. I know how much ram each guest has configured but that is not
enough. I need to know how much the system has available, and just reading
the free memory statistic does not help much since that is only a snapshot
- when running a guest you can have 1gb free now, and 10 mb free 2 min
later.
Any ideas?
Thanks,
Andrei

[libvirt-users] Remote Vbox connection to windows host
by Pavlo Shchelokovskyy
Hi all,
I'd like to use libvirt to control/have access to virtual machines created
with VirtualBox _on a Windows host_ (from the Linux guest of the same
Windows-hosted VirtualBox). It is for testing purposes only,, so security
does not matter much. Is it possible at all? I have some troubles
understanding the note in bold at https://libvirt.org/drvvbox.html. Does
that mean that one has to have a (running) libvirt daemon on the same host
where VirtualBox is running to have a remote connection to this hypervizor
with libvirt?
Best regards,

[libvirt-users] Adding a Virtio Serial Controller
by Jean-Pierre Ribeauville
H,
As I want to add a channel device programmatically via libvirt API , I got an error due to the fact
that the Guest has no VirtIO Serial Controller in its configuration.
Is it possible to add it via libvirt API ?
Thx for help.

[libvirt-users] executing libvirt commands as a different user
by Andrei Perietanu
I am using the libvirt API to manage VMs on the system, using a python
wrapper to execute commands.
I need to allow a webserver to access these commands and mostly read
information about the VMs. The problem is that when using the web interface
you use are basically running the commands as different user. Since
libvirtd is run as root by default you get permission errors.
Is there any way of getting around this without using polkit?
Thanks,
Andrei

[libvirt-users] Error after failed external snapshot.
by Dominique Ramaekers
Hi,
I use this procedure to backup my VM's: http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit
It works on my current host:
Compiled against library: libvirt 1.2.16
Using library: libvirt 1.2.16
Gebruikte API: QEMU 1.2.16
Draaiende hypervisor: QEMU 2.1.0
Now I'm doing a test on a testing host:
Compiled against library: libvirt 1.2.21
Using library: libvirt 1.2.21
Gebruikte API: QEMU 1.2.21
Draaiende hypervisor: QEMU 2.5.0
The first time, the active block commit failed because the block action was stuck on 100% and I got this error:
'block copy still active: disk 'vda' not ready for pivot yet'
I did a 'virsh blockjob PCVIRT1 vda -abort' and started 'virsh blockcommit PCVIRT1 vda --active --verbose -pivot' again. This way, the external snapshot was commited ok.
Now I get this error when I want to create an external snapshot:
fout: internal error: kan QEMU commando 'transaction' niet uitvoeren: The feature 'snapshot' is not enabled
I can't find a lot of information about this. Some help will be appreciated.
Greetings,
Dominique.

Re: [libvirt-users] channel device "state" value missing within OpenStack Kilo version

It works fine.

Objet : channel device "state" value missing within OpenStack Kilo version
Hi,
I've installed a OpenStack KILO all-in-one .
For private need , I've to add a channel device to all my GUESTS on my compute node.
It works fine (e.g. via a virsh command).
Problem is that , in the xml describing the Guest , this 'state' value :
<target type='virtio' name='agent' state='disconnected'/>
showing if the channel is connected on the Guest side is missing.
Does it mean that some qemu/KVM components are too old within KILO OpenStack release ?
FYI , here are the installed related packages versions coming with KILO:

[libvirt-users] channel device "state" value missing within OpenStack Kilo version
by Jean-Pierre Ribeauville
Hi,
I've installed a OpenStack KILO all-in-one .
For private need , I've to add a channel device to all my GUESTS on my compute node.
It works fine (e.g. via a virsh command).
Problem is that , in the xml describing the Guest , this 'state' value :
<target type='virtio' name='agent' state='disconnected'/>
showing if the channel is connected on the Guest side is missing.
Does it mean that some qemu/KVM components are too old within KILO OpenStack release ?
FYI , here are the installed related packages versions coming with KILO:

[libvirt-users] unable to dissect libvirt rpc packets using wireshark plugin
by gowrishankar
Hi,
I am trying libvirt plugin in wireshark to dissect RPC payload in TCP, but
finding dissector code not really working.
My env is Fedora core 21 (x86_64) and installed packages are as follow:
wireshark-1.12.6-1.fc21.x86_64
libvirt-wireshark-1.2.9.3-2.fc21.x86_64
Earlier, just after installation, I noticed libvirt.so available only in
/usr/lib64/wireshark/plugins/1.12.5/ . Wireshark could not load libvirt
plugin.
So, I copied above .so into 1.12.6/ under same plugins folder, following it
wireshark could list libvirt as supported protocol.
tshark -G protocols | grep libvirt
Libvirt libvirt libvirt
However, on checking with some pcaps which has libvirt RPC calls captured on
wire, wireshark does not list libvirt RPC packets, as I search for "libvirt"
protocol in pcap.
Have anyone experienced this before or if you have any pointer that I could
check in my env, that would be very helpful.

[libvirt-users] Trouble with volume permissions
by Frank Laszlo
I'm working on an integration that uses QCOW2 volumes with backing stores.
I have qemu configured to run as the "qemu" user, which seems to be fine. I
now need to make sure my volumes are readable by this user. However, it
seems the volume being created is owned by root, instead of "qemu" as I'd
expect it to be. I tried various things and was unable to get it to create
the file as the correct user. I've supplied a link to the XML I'm using to
create the volumes. If anyone has any ideas it would be massively helpful.
Thanks
