[libvirt-users] Statistics domain memory block when domain shutdown
by llilulu
Hi
My libvirt version is 3.4.0,host system is centos 7.4 ,kernel is 3.10.0-693.el7.x86_64 , when I shutdown domain in virtual system, My program call virDomainMemoryStats, My program blocked in this api. the call stack is
#0 0x00007ff242d78a3d in poll () from /lib64/libc.so.6
#1 0x00007ff243755ce8 in virNetClientIOEventLoop () from /lib64/libvirt.so.0
#2 0x00007ff24375654b in virNetClientSendInternal () from /lib64/libvirt.so.0#3 0x00007ff2437579b3 in virNetClientSendWithReply () from /lib64/libvirt.so.0

#8 0x00007ff22ee975c2 in VM::getMemoryStats (this=0x7ff1d4064ae0,
Begin I think is my program problem, But when I use virsh domstats cmd , The cmd block too. In my program, I set timeout event for virConnectPtr. But my program blocked all the time. I find my system log, I find some libvirtd error:

Is this problem a bug or I can't statistics some specifi status domain?

[libvirt-users] Lib virt v4.x packages for Xenial
by Stephen Bates
Hi Libvirt Users!
Apologies in advance as I am sure this has been asked before (but I could not find it in the archives).
Has anyone had any success creating .deb packages for Xenial for libvirt and libvirt-bin for v4.0 or v4.1? A quick scan of the PPA respository does not show anything this recent.
Is there a fundamental issue that prevents these package files being created? If so has anyone got a primer for how best to install a recent version of libvirt and associated tools on Xenial? We have a bare-metal server we have to keep on LTS but I need to be able to run recent versions of QEMU to get access to certain NVMe model features that were only recently added...
Cheers
Stephen

Hello Everyone,
My pc run in CentOS 7.4 and install libvirt-4.0.0 + Qemu-kvm 2.9.0 + Ceph
10.2.10 ALL-in-One.
I use python-sdk with libvirt and run [self.domain.updateDeviceFlags(xml,
libvirt.VIR_DOMAIN_AFFECT_LIVE)] on CDROM (I want to change media path).
However, I enable libvirt debug log , the log as below:

I see the flow is virDomainUpdateDeviceFlags -> qemuMonitorChangeMedia, but
the cephx auth is drop, so make update error. Anybody meet this error?

[libvirt-users] Can't shutdown/reboot Windows 10 guest if on lock screen
by Sebastian Arcus
I am running Windows 10 vms on a Linux host with libvirt 4.0.0 and qemu
2.10.2
I can shutdown and reboot the Windows 10 guests if the no user is logged
in the vm, or if the user is logged in and active/seeing the desktop.
But after a while, when the lock screen kicks in (but the user is still
logged in technically), the shutdown and reboot commands don't have any
effect any more. Is there any way around this (except for disabling
automatic screen locking on Windows)?
Thank you for any hints.

[libvirt-users] How can we achieve vga emulation over a serial port in libvirt
by Meina Li
Hi
For the latest seabios version, it said: Support for vga emulation over a
serial port in SeaBIOS (sercon).
So I want to know how can I find the application of this feature in
libvirt? And whether my understanding is correct?
There are no related instruction on the website: https://libvirt.org/
My understanding:
(1) The feature means: we can set this the IO address of a serial port to
"video" element to enable SeaBIOS' VGA adapter emulation on the given
serial port.
(2) Libvirt XML examples and with this xml the guest can start successfully:
<controller type='virtio-serial' index='0'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06'

</controller>
<video>
<model type='vga' vram='16384' heads='1' primary='yes'/>

[libvirt-users] NIC cannot unplug
by llilulu
Hi:
I encounter a promble, when I start a domain(only a blank disk, not install system), I can hotplug NIC, But I cannot hot unplug NIC.
I consider the domain start from a blank disk, not install system, so the domain haven't virtio too, I suspect virtio problem.
But I cann't confirm. Can any one tell me?
Thanks
