[libvirt-users] LibVirt "make install" after successful compilation
by Azizul Hakim
I am having some issue with LibVirt installation from source code. I
downloaded the latest code from git, was able to configure and compile it.
But when I try to install it using *sudo make installi, *I get the
following errors.
Making install in po
make[1]: Entering directory '~/libvirt/po'
make[2]: Entering directory '~/libvirt/po'
make[2]: Nothing to be done for 'install-exec-am'.
make install-data-hook
make[3]: Entering directory '~/libvirt/po'
make[3]: *** No rule to make target 'af.gmo', needed by
'install-data-hook'. Stop.
make[3]: Leaving directory '~/libvirt/po'
Makefile:2027: recipe for target 'install-data-am' failed
make[2]: *** [install-data-am] Error 2
make[2]: Leaving directory '~/libvirt/po'
Makefile:1981: recipe for target 'install-am' failed
make[1]: *** [install-am] Error 2
make[1]: Leaving directory '~/libvirt/po'
Makefile:2105: recipe for target 'install-recursive' failed
make: *** [install-recursive] Error 1
As I mentioned, there is no error during compiling the source code. It
would be helpful if someone could point me in a direction so I can figure
out the problem.
Thanks

[libvirt-users] qemu crash, qemu_thread_create: Resource temporarily unavailable
by llilulu
Hi
My qemu is 2.9.0, libvirt is 3.4.0.
I start many guest in short time(128G pyhsical memory ,1G per guest, 90 guest), and then run memtest on guest system.memtest just occupy guest memory，so when run memtest, host will allocate memory for guest. I run memtest on all my guest, and some guest will encounter crash. qemu log has qemu_thread_create: Resource temporarily unavailable record，I ask same question before, replier suggest I change qemu.conf max_process arg, but I cat /proc/$pid/limits, I find maxprocess limit is very big, I don't think is the args restrict. I think is when I run memtest on all guest, the host pressure very highly in short time, because when I run memtest on all guest, i encounter some other program core, I use gdb debug the core, I find is dump in allocate memory. so I want known qemu crash is that reason, and how host system acceptable pressure limit. when I encounter qemu crash, what can I do avoid the promble.
Thanks

[libvirt-users] Possible to resize a Windows guest's disk while online?
by Andre Goree
I'm looking for a way to online resize a Windows disk -- i.e., be able
to resize the disk without shutting down, rebooting, or detaching the
disk.
Is this at all possible? Or am I just barking up the wrong tree? I'm
not finding a way to do this and even Amazon has a weird workaround, in
which the user must write data to the newly resized-drive in order to
recognize the new size without taking the disk or the VM offline.
[Obligatory] YAY Microsoft.

[libvirt-users] qemu: qemu_thread_create: Resource temporarily unavailable
by llilulu
Hi:
My libvirt is 3.4.0 and qemu is 2.9.0, My host has a big memory(128G), I run many guest on my host(80 guests), when I batch stop and start guests, some guest will crash, the qemu log is "qemu: qemu_thread_create: Resource temporarily unavailable". I search qemu code, I find qemu_thread_create just like pthread_create function. I search on internet, someone say that is a bug of qemu.Because my host run many guest ,so I cann't ensure whether qemu bug or my host load heavy cause my guest crash. Can someone tell me what reason cause the promble? and what can I do avoid the promble?
Thanks

[libvirt-users] can't find how to solve "QEMU guest agent is not connected"
by Matt
I am trying to make Qemu agent work with libvirt thanks to
https://github.com/NixOS/nixops/pull/922 with libvirt 4.1.0. I've been
trying to make it work for quite some time but I still haven't the
slightest idea of what is wrong, I keep seeing "Guest agent is not
responding: QEMU guest agent is not connected" as the program I use
(nixops) calls the libvirt python API.
I apologize in advance for dropping so many details but in case
someone is interested in answering this post, I thought I would
provide details upfront.
The failure surprises me as typically a socket is created when I start
the VM with a priori the correct rights myuser:libvirtd (libvirtd is
the default libvirt group on nixos, different from upstream IIRC):
/var/lib/libvirt/qemu/channel/target/domain-10-nixops-3cb2c9c2-41ea/org.qemu.guest_agent.0
My domain contains
```
<channel type='unix'>
<target type='virtio' name='org.qemu.guest_agent.0'/>
<address type='virtio-serial' controller='0' bus='0' port='1'/>
</channel>
```
as requested per the doc (I tried with source=bind to no avail, btw
the doc for `source` is not that great)
my libvirtd.conf has the following setting
```
log_level = 1
# no filter for now
log_filters="1:qemu.qemu_agent 1:qemu.qemu_monitor"
# log_filters="3:remote 4:event 3:json 3:rpc"
log_outputs="1:file:/var/log/libvirt/libvirtd.log"
```
`journalctl -b -u libvirtd.service` returns
```

[libvirt-users] How allocate ip for guest in xml file
by llilulu
Hi:
I encounter a promble when I use libvirt manager my virtual machine. I use dhcp allocate IP for my guest, but use dhcp manager IP source, I will ensure guest run NetworkManager auto start NIC in dhcp type get IP. But some release system no install NetworkManager, or some installed system no install NetworkManager, so when I manager those guest, I cann't allocate IP for guest via dhcp server. I want know has other way allocate ip for guest in guest xml file when create the guest, I search "libvirt domain xml format", I find use blow xml configuration in <interface/>
<ip address='192.168.122.5' prefix='24'/>
But I add this in my guest xml file, virsh create guest will report an error:
"error: unsupported configuration: Invalid attempt to set network interface guest-side IP route and/or address info, not supported by QEMU"
I want to know if I use dhcp allocate IP for guest, has some way auto start guest dhclinet when guest start(because NIC can hotplug, I cann't write NIC configure file for it). or I want configure IP for guest in guest xml file,How cant I do? my libvirt version is 3.4.0, qemu is 2.9.0. I compile libvirt and qemu myself, when compile its run ./configure script without specific args. If I want qemu or libvirt support configure IP in guest xml file, how I compile libvirt and qemu?
Thanks.

[libvirt-users] Online Disk Resize with Windows Server 2016
by Andre Goree
I'm having an issue when resizing a disk (a Ceph RBD disk, though the
type of disk shouldn't matter, I'd think) attached to a Windows Server
2016 guest.
After I resize the disk, the newly-created disk space is _not_
recognized by the server. Even after running Action > Rescan from the
Disk Management app, the new disk space does not show. However, when I
perform the same resize on a Windows Server 2012 or even a Sever 2008
system, the Action > Rescan works fine and the newly-created disk space
is recognized without needed to detach the drive or reboot the VM.
Does anyone have an idea of what may have changed in Windows 2k16 that
might be causing this? Possibly some undocumented registry change or
something?

Huh, I remember seeing different error when trying this (although I'm
using gcc). However, I suspect '-Wl,-z -Wl,defs' arguments are problem.
We add them onto linker cmd line. You can try applying this patch and
see if it helps:
