[libvirt-users] Installing QEMU from source causing error
by Probir Roy
Hi,
I am trying to run Qemu-4.0 installed from source code.
When I run virt-manager to create a VM, I get the following error:
```
Unable to complete install: 'internal error: process exited while

```
I configured the Qemu with following command:
```
./../configure --prefix=/usr --enable-spice --target-list=x86_64-softmmu
--enable-kvm --enable-debug --enable-libssh2
```
Is it that I missed enabling any configuration while installing Qemu? What
is the expected QEMU configuration to run with libvirt?

[libvirt-users] virsh edit has no impact on domain
by Probir Roy
Hi,
I am using "virsh edit" to edit a domain. After edit it says
>> Domain ubuntu18.04 XML configuration edited.
However, reopening the domain with "virsh edit" shows old file.
The domain is also turned off.
$virsh list --all --persistent
Id Name State
----------------------------------------------------
- ubuntu18.04 shut off
I have also tried running "virsh define" to set new configuration.
$virsh define ubuntu18.04.xml
>>> Domain ubuntu18.04 defined from ubuntu18.04.xml
However, it also did not change the file. How can I edit the domain config
file?
OS: Ubuntu 18.04.1
virsh: 4.0.0

[libvirt-users] domain xml questions
by Vasiliy Tolstov
Hi!
If i want to use bridged network or openvswitch, does guestfwd only
works with slirp network? Or how it work in case of using
bridge/openvswitch?
<devices>
<channel type='unix'>
<source mode='bind' path='/tmp/guestfwd'/>
<target type='guestfwd' address='10.0.2.1' port='4600'/>
</channel>
</devices>
If this cant't work with provided network types, how can i create
inside guest serial console on 10 tty that binded to listening unix
domain socket on host system?

[libvirt-users] Preloading shared library with libVirt
by Probir Roy
Hi,
I am trying to preload two shared libraries while running Qemu using
libvirt. To preload the shared libraries I have added an environment
variable in the $domain.xml file with the following command:
```
virt-xml generic --edit --confirm --qemu-commandline
'env=LD_PRELOAD=/home/probir/Downloads/kpv_temp/temp/kvmTest/build_kvm/libperform.so:/home/probir/Downloads/kpv_temp/temp/kvmTest/dependencies/libmonitor/installDir/lib/libmonitor.so'
```
However, while running the domain, I get the following message of failure
to preload the shared files in the log.

I cannot figure out what is causing the failure of preload. Previously, I
manually preloaded the same shared libraries for other application.

[libvirt-users] filesharing file owner problem
by Vojto Ľach
Hello,
I'm having an issue with usage of libvirt driven qemu where I'm sharing
directory with guest machine.
virsh domain filesharing configuration:
<filesystem type='mount' accessmode='passthrough'>
<driver type='path' wrpolicy='immediate'/>
<source dir='/media/share'/>
<target dir='data'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07'
function='0x0'/>
</filesystem>
/etc/libvirt/qemu.conf :
user = "root"
group = "root"
dynamic_ownership = 0
clear_emulator_capabilities = 0
even with this unsecure configuration I wasn't able to achieve that newly
created files/dirs in guest machine have ownership of guest machine user
but they are still created under root user id. Also strange is that group
of those files/dirs are correct.
Can somebody help me with this?
Thank you.

As a result `virsh capabilities` as root returns nothing:

whereas running as a regular user works fine:

and by extension, running VMs as regular user works fine via
qemu:///session , but qemu:///system does not work.
It seems like setgroups is failing:
https://github.com/libvirt/libvirt/blob/v5.5.0/src/util/virutil.c#L1045-L...
Is this the expected behaviour?

[libvirt-users] Question regarding using multiple physical functions inside a network pool.
by Mohamed, Faris
Hello,
I was planning on adding multiple physical functions using the built in SR-IOV features offered by libvirt to a create a bigger pool of virtual functions using the
<forward mode='hostdev' managed='yes'> heading
(I want to be able to use more virtual machines then there are virtual functions available on an ethernet port).
As soon as I try to define multiple physical functions in a pool, I get this error:
error: Failed to define network from biggernetwork.xml
error: XML error: Only one <pf> element is allowed in <forward> of network bigger network
when using this command:
sudo virsh net-define biggernetwork.xml
on the following XML document:
<network>
<name>bigger network</name>
<forward mode='hostdev' managed='yes'>
<pf dev='eth5'/>
<pf dev='eth7'/>
</forward>
</network>
It seems that you are not able to add multiple physical functions to this network to create a pool of more virtual functions.
Is there anyway that you can do this using that I am missing? I seem to be looking at the documentation and there seems to be nothing related to this. I think this would be extremely useful and would make automate adding virtual functions to virtual machines much easier to manage.
Thanks in advance,
Faris

Hi,
at first I'd like to ask you to CC the libvirt-users or libvir-list with
such kind of questions (questions implying regression of behaviour are
okay on the development list).
I've CC'd libvirt-users with this reply to archive this.
Also I'd strongly encourage you _not_ to use HTML formatting on
thechnical communications. As you can see I'm using a plain-text mail

That one does not seem to be related to your issue.
It simply assumes that when starting a qemu process (so nothing really
related to any of the vol-* and pool-* virsh APIs) when the disk is
referencing a volume from the storage driver and the referenced volume
is a directory, then we assume that qemu should use 'fat' as the driver.

I'll have to cut off everything here and replace it with a non-HTML

I've looked at the git history and didn't find anything that could be
related here unfortunately. I'm also not very familiar with RBD in
libvirt.

So this is really weird. The error message is produced if the target
format is not 'raw' but the above command clearly supplies it.
I'd suggest you collect debug logs while trying both and attach them
here. Unfortunately I don't see what could be wrong here.

[libvirt-users] UDP broadcasts vs. nat Masquerading issue
by Nikolai Zhubr
Hi all,
I'm observing an issue that as soon as libvirt starts, UPD broadcasts
going through physical network (and unrelated to any virtualization) get
broken. Specifically, windows neighbourhood browsing through samba's
nmbd starts suffering badly (Samba is running on this same box).
At the moment I'm running a quite outdated version 1.2.9 of libvirt, but
other than this issue, it does its job pretty well, so I'd first
consider some patching/backporting rather than totally replacing it with
a new one. Anyway, I first need to better understand what is going on
and what is wrong with it.
This could also be related somewhat to
https://www.redhat.com/archives/libvir-list/2013-September/msg01311.html
but I suppose it is not exactly that thing.
I've already figured the source of trouble is anyway related to these
rules added:
-A POSTROUTING -o br0 -j MASQUERADE
-A POSTROUTING -o enp0s25 -j MASQUERADE
-A POSTROUTING -o virbr2_nic -j MASQUERADE
-A POSTROUTING -o vnet0 -j MASQUERADE
Here, virbr2_nic and vnet0 are used by libvirt for arranging network
configurations for VMs, ok. However, br0 is a main interface of this
host with primary ip address, with enp0s25 being a physical nic of this
host, and it is used for all sorts of regular (unrelated to
virtualization) communications. Also, br0 is used for attaching bridged
(as opposed to NATed) VMs managed by libvirt.
Clearly, libvirt somehow chooses to set up masquerading for literally
all existing network interfaces here (except lo), but I can't see a real
reason for the first two rules in the list above. Furthermore, they
corrupt UDP broadcats coming from outside and reaching this host
(through enp0s25/br0) such that source address gets replaced by this
hosts primary address (as per masquerading). I've verified this by
arranging a hand-crafted UDP listener and printing the respective source
addresses as seen by normal userspace.
Now I've discovered that I can "eliminate" the problem by either:
1. Removing "-A POSTROUTING -o br0 -j MASQUERADE" (manually)
2. Inserting "-A POSTROUTING -s 192.168.0.0/24 -d 192.168.0.255/32 -j
ACCEPT"
(Of course correcting rules by hand is not a solution, just a test)
So question is, how the correct rules should ideally look like? And, is
this issue known/fixed in most current libvirt?
Thank you,
Regards,
Nikolai
