The pthreads library is a mandatory part of libvirt, so we can't
skip that.
Can you provide your "config.log" file - if it is larger than
200 KB, please compress it, or upload it somewhere

Daniel

[libvirt-users] Starting VM fails with: "Setting different DAC user or group on /path... which is already in use" after upgrading to libvirt 5.6.0-1
by Nir Soffer
Hi,
I upgraded to a Fedora 29 host using virt-preview repo to
libvirt-daemon-5.6.0-1.fc29.x86_64
The host was using plain Fedora 29 without virt-preview before that.
After the upgrade, starting some vms that were running fine fail now with
this error:
Error starting domain: internal error: child reported (status=125):
Requested operation is not valid: Setting different DAC user or group on
/home/libvirt/images/voodoo4-os.img which is already in use
Traceback (most recent call last):

Requested operation is not valid: Setting different DAC user or group on

These vms we created by creating one vm, and the cloning the vms.
I tried to delete the disks and add them back in one of the vms, but the vm
still fail with the
same error.
I hope that someone have a clue what is the issue, and how it can be fixed.
Here some details about the setup:

[libvirt-users] Compiling Libvirt on Windows for Hyper V support

Does anyone have any experience compiling Libvirt on a windows machine ? Specifically I am trying to enable hyper-v domain on Libvirt.

[libvirt-users] Libvirt API for attaching volume to domain
by Varsha Verma
Hi,
I wanted to know if there is any Python API exposed for libvirt using which
I can attach a libvirt volume to a libvirt domain/VM.
I intend to do something similar to the `attach-disk` command of virsh
using python.

[libvirt-users] OVS / KVM / libvirt / MTU
by Sven Vogel
Hey there,
I hope anyone can bring some light in the following problem.
<interface type='bridge'>
<source bridge='cloudbr0'/>
<mtu size='2000'/>
<mac address='02:00:74:76:00:01'/>
<model type='virtio'/>
<virtualport type='openvswitch'>
</virtualport>
<vlan trunk='no'>
<tag id='2097'/>
</vlan><link state='up'/>
</interface>
we have an base bridge for example and cloudbr0. After we add an mtu to the vm bridge here it seems the base bridge gets the same mtu like the vnet adapter.
Is this normal behaviour of libvirt together with OVS?
—ovs-vsctl show
5b154321-534d-413e-9761-60476ae06640
Bridge "cloudbr0"
Port "cloudbr0"
Interface "cloudbr0"
type: internal
—MTU from the bridge after set an MTU into the XML File (before we had here 9000)
mtu : 2000
mtu_request : []
name : "cloudbr0"
ofport : 65534
—MTU of the vnet interface
mac_in_use : "fe:00:74:76:00:01"
mtu : 1450
mtu_request : 1450
name : „vnet2"
Thanks for help…

[libvirt-users] Vm in state "in shutdown"
by 马昊骢 Ianmalcolm Ma
Description of problem:
libvirt 3.9 on CentOS Linux release 7.4.1708 (kernel 3.10.0-693.21.1.el7.x86_64) on Qemu version 2.10.0
I’m currently facing a strange situation. Sometimes my vm is shown by ‘virsh list’ as in state “in shutdown” but there is no qemu-kvm process linked to it.
Libvirt log when “in shutdown” state occur is as follows:
“d470c3b284425b9bacb34d3b5f3845fe” is vm’s name, remoteDispatchDomainMemoryStats API is called by ‘collectd’, which is used to collect some vm running states and host information once every 30’s.

I’ve tried to find out how did this problem happened. I analyzed the execution process of the job and speculated that the problem occurred as follows:
step one: libvirt send command 'system_powerdown' to qemu.
step two: libvirt receive qemu monitor close event, and then deal EOF event.
step three: remoteDispatchDomainMemoryStats job start on the same vm.
step four: work thread dealing stop job is waited on job.cond, the timeout is 30s.
It seems that the remoteDispatchDomainMemoryStats job is too slow to let the stop job wait timeout.
Then I tried to reproduce this process. The step is as follows:
First step: add a sleep on ‘qemuProcessEventHandler' by using pthread_cond_timedwait. So can execute 'virsh dommemstat active’ command at this time interval.
Second step: start a vm to test
Third step: execute 'virsh shutdown active’ to shutdown the vm
Fourth step: execute 'virsh dommemstat active’ when stop job is sleep.
Then it works. The test vm state became to 'in shutdown’, and the libvirt log is as follows:
“active” is my test vm’s name.

I found that on function ‘qemuMonitorUpdateWatch’, if mon->watch is zero, then event would’t be update. But 'qemuMonitorSend'
would still wait on mon->notify. So the remoteDispatchDomainMemoryStats job is blocked, and then the stop job blocked too.
618 static void
619 qemuMonitorUpdateWatch(qemuMonitorPtr mon)
620 {
621 int events =
622 VIR_EVENT_HANDLE_HANGUP |
623 VIR_EVENT_HANDLE_ERROR;
624
625 if (!mon->watch)
626 return;
627
628 if (mon->lastError.code == VIR_ERR_OK) {
629 events |= VIR_EVENT_HANDLE_READABLE;
630
631 if ((mon->msg && mon->msg->txOffset < mon->msg->txLength) &&
632 !mon->waitGreeting)
633 events |= VIR_EVENT_HANDLE_WRITABLE;
634 }
635
636 virEventUpdateHandle(mon->watch, events);
637 }
I try to fix this bugs by add a judgment before qemuMonitorUpdateWatch, and it seem works.
1046 int
1047 qemuMonitorSend(qemuMonitorPtr mon,
1048 qemuMonitorMessagePtr msg)

1091 cleanup:
1092 mon->msg = NULL;
1093 qemuMonitorUpdateWatch(mon);

I’m not really sure that this change will affect other process.

[libvirt-users] libvirt/dnsmasq is not adhering to static DHCP assignments
by Christian Kujau
This is basically a continuation of an older posting[0] I found, but
apparently no solution has been posted. So, I'm trying to setup static
DHCP leases with dnsmasq that is being started by libvirtd:
-----------------------------------------------------------
$ sudo virsh net-dumpxml --network default
<network>
[...]
<dns enable='no'/>
<ip address='192.168.122.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.122.130' end='192.168.122.250'/>
<host mac='08:00:27:e2:81:39' name='f30' ip='192.168.56.139'/>
-----------------------------------------------------------
And the domain is indeed being started with that hardware address:
-----------------------------------------------------------
$ virsh dumpxml --domain f30 | grep -B1 -A3 mac\ a
<interface type='bridge'>
<mac address='08:00:27:e2:81:39'/>
<source bridge='virbr0'/>
<target dev='tap0'/>
<model type='virtio'/>
-----------------------------------------------------------
But for some reason the domain gets a different address assigned, albeit
from the correct DHCP pool:
-----------------------------------------------------------
$ ssh 192.168.122.233 "ip addr show"
[...]
2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state
UP group default qlen 1000
link/ether 08:00:27:e2:81:39 brd ff:ff:ff:ff:ff:ff
inet 192.168.122.233/24 brd 192.168.122.255 scope global dynamic enp1s0
-----------------------------------------------------------
See below for even more details. I've removed the virbr0.status file,
restarted the network, still it gets this .233 address instead of the
configured .139. Also, I'm not able to add a debug log to the
libvirtd/dnsmasq instance, although it should be possible[1], the
xmlns:dnsmasq stanza is overwritten as soon as the configuration is saved.
Short of a debug (queries) log, strace on the libvirtd/dnsmasq process
reveals that the client seems to request this strange IP address:
23002 19:01:59.053558 write(11, "<30>Jul 31 19:01:59 dnsmasq-dhcp[23002]: DHCPREQUEST(virbr0) 192.168.122.233 08:00:27:e2:81:39 ", 95) = 95
23002 19:01:59.054024 write(11, "<30>Jul 31 19:01:59 dnsmasq-dhcp[23002]: DHCPACK(virbr0) 192.168.122.233 08:00:27:e2:81:39 f30", 94) = 94
So I restarted the dhclient process in the domain (a freshly installed
Fedora 30), removed all state files with "192.168.122.233" in them, but
still the domains gets assigned the .233 instead of the .139 address.
The next step would be to disable libvirtd/dnsmasq altogether and run my
own dnsmasq instance, but I wanted to avoid that. Any idead on where to
look next?
Thanks,
Christian.

[libvirt-users] Reg: content of disk is not reflecting in host.
by bharath paulraj
Hi Team,
I am doing a small testing and I don't know if my expectation is correct or
not. Pardon me if I am ignorant.
I created a VM and the VM is running. In the hypervisor I have created
".img" file and attached this .img file to the VM.
My expectation is that, if VM is writing files to the attached disk, then
it should reflect in the .img file created in the hypervisor. But It is not
working as my expectation.
Please correct me if my expectation is wrong.
Steps:
1. Created disk.img in the hypervisor using the command: dd if=/dev/zero
of=disk.img bs=1M count=50; mkfs ext3 -F disk.img
2. Attached the disk to the running VM using the command: virsh attach-disk
<Domain-Name> --source disk.img --target vdb --live
3. In the VM, I mounted the disk and created few files.
4. In the hypervisor, I mounted the disk.img to check if the file created
in the VM exists in the .img file.
>> I am not able to see those files.
Regards,
Bharath
