[libvirt] [PATCH v2] esx: Allow 'vmpvscsi' as SCSI controller model
by Matthias Bolte
---
v2:
- rename 'pvscsi' to 'vmpvscsi'
- add esxVMX_SCSIControllerModelType{to,from}String to handle the difference
between VMX and XML name of the controller model

[libvirt] [PATCH] Fix SEGV on exit after domainEventDeregister()
by Philipp Hahn
When the last callback is removed using domainEventDeregister(), the
events dispatcher is deregistered from the C-library, but
domainEventsCallbacks is still an empty list.
On shutdown __del__() deregisters the dispatacher again, which SEGVs
# You need the event-loop implementation from the Python examples;
# give the file a name which is importable by Python.
ln examples/domain-events/events-python/event-test.py eloop.py
python -c 'from eloop import *
import sys
def dump(*args): print " ".join(map(str, args))
virEventLoopPureStart()
c = libvirt.open("xen:///")
c.domainEventRegister(dump, None)
c.domainEventDeregister(dump)
sys.exit(0)'
domainEventDeregister() needs to delete domainEventCallbacks so subsequent
calls to __del__() and domainEventRegister() choose the right code paths.
Setting it to None is not enough, since calling domainEventRegiser() again
would trigger an TypeError.

[libvirt] problems using virt-manager with qemu-kvm to boot a windows from floppy
by John Lumby
Background :
I have an existing win2K system which consists of one boot-floppy image (boot device) and one hard-disk partition /dev/sdc1). Previously I got this running with virt-manager and qemu-0.11 with kqemu - after hitting one bug in virtinst concerning name of the floppy and applying fix from Cole
http://hg.fedorahosted.org/hg/python-virtinst/rev/4d0ea2274ffd
Yesterday:
tried running same win2k but on a different system - the machine has the Intel VT-x - OS still Fedora 13, using qemu-kvm.
I applied the above patch to this system's virt-inst, and tried basically same virt-install command other than to select virt-type of kvm instead of kqemu
virt-install --connect qemu:///system --name=OCFwin2k --ram=392 --cpuset=0 --description="win2k on OCFed disk on usb, nat network" --import --network=network=default,model=pcnet --virt-type=kvm --accelerate --vnc --vncport=5905 --video=cirrus --disk=/home/lumby/Downloads/win2k_boot.floppage,device=floppy --disk=/dev/sdc,device=disk --os-type=windows --os-variant=win2k
But this time I hit two new problems :
. another (different) one relating to the floppy - qemu-kvm couldn't find it
. wrong syntax for the usb tablet in qemu-kvm command meant no tablet.
The qemu-kvm command that virt-manager came up with was this:
/usr/bin/qemu-kvm -S -M fedora-13 -cpu n270,+x2apic -enable-kvm -m 392 -smp 1,sockets=1,cores=1,threads=1 -name OCFwin2k -uuid 8a63ef02-cea8-cc23-5a31-f98a1b0bdea1 -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/OCFwin2k.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=localtime -boot a -drive file=/home/lumby/Downloads/win2k_boot.floppage,if=none,id=drive-fdc0-0-0 -global isa-fdc.driveA=drive-fdc0-0-0 -drive file=/dev/sdc,if=none,id=drive-ide0-0-0 -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -device pcnet,vlan=0,id=net0,mac=52:54:00:97:f6:b9,bus=pci.0,addr=0x4 -net tap,fd=45,vlan=0,name=hostnet0 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -device usb-tablet,id=input0 -vnc 127.0.0.1:5 -k en-us -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3
I've attached at the bottom the xml that virst-inst built for this machine.
I then looked back at what qemu command the virt-manager on my other system had come up with, merged bits of that with the above, and came up with this one which worked ok. It's a whole lot simpler!
/usr/bin/qemu-kvm -M fedora-13 -m 392 -smp 1 -name OCFwin2k -localtime -boot a -drive file=/home/lumby/Downloads/win2k_boot.floppage,if=floppy,unit=0 -drive file=/dev/sdc,if=ide,bus=0,unit=0 -net nic,macaddr=52:54:00:d7:84:4e,vlan=0,name=net0 -net tap,fd=17,vlan=0,name=hostnet0 -serial pty -parallel none -usb -usbdevice tablet -vga cirrus
I think there must be a bug or two somewhere but whether in virt-manager or in virt-inst or both I don't know. If you want more information just ask.

[libvirt] [PATCH] pciSharesBusWithActive fails to find multiple devices on bus
by Chris Wright
The first conditional is always true which means the iterator will
never find another device on the same bus.
if (dev->domain != check->domain ||
dev->bus != check->bus ||
----> (check->slot == check->slot &&
check->function == check->function)) <-----
The goal of that check is to verify that the device is either:
in a different pci domain
on a different bus
is the same identical device
This means libvirt may issue a secondary bus reset when there are devices
on that bus that actively in use by the host or another guest. Not good.
Fix the typo.

[libvirt] libvir: Domain error <domName>: invalid argument in virDomainGetXMLDesc
by Priya
All,
I just downloaded and installed *libvirt-bin* and this is my first email to
the group, so I apologize in advance if my questions are too naive!
So, I am trying to access VMs running on* xen3.2 hypervisor* (host with
kernel *2.6.24-24-xen*) using *virt-manager* installed on a machine
running*Ubuntu 9.04
* (client machine). I got to the point where I can connect to my virtual
machine and my domain-0 through the* virt-manager* client (meaning that I
already have *libvirt*,* ssh-askpass* downloaded and the *libvirtd* and *
xend* running on my host machine), and on the client machine I can view the
window showing the statistics of CPU utilization of my domain-0 and user
domain. The attachment shows a shapshot of the *virt-manager* on my client
machine.
Now when I try to access the GUI of either of domain-0 or the user domain
(by selecting the specific domain and clicking open) I get the following
error message in a pop-up on my client and in the libvirtd console on the
host:
"*libvir: Domain error xen_2: invalid argument in virDomainGetXMLDesc*"
I tried to Google this error, but I don't find any clear answers. It
*seems*to be a bug in the
*libvirt* implementation that has been detected and resolved already. And I
am confused as to why is it that such a recent version is still buggy?
Should I have downloded another version instead? I desperately wish to
resolve this problem and would appreciate any guidance.
Many thanks!

[libvirt] Compiling C++ program with libvirt
by adrian wyssen
Hi everyone
I am trying to compile a C++ program which uses libvirt to connect to an
ESXi host. I got the code running if I wrote it in C, directly in the
hellolibvirt.c example. However, I am now trying to compile that code in a
C++ file which is not inside the example directory.
I tried to compile with the following command:
g++ -g -D debug=1 -c -llibvirt ESXWrapper.cpp
g++ -g -D debug=1 -o ESXWrapper ESXWrapper.o
The first line passes and creates ESXWrapper.o file. But when I run the
second line, it gives me the following error:

Can anybody give me a hint, how to link correctly to libvirt. And also tell
me, if there are special functions to use with C++, other than the examples
provided in the source code, which are written in C.
Thank you

[libvirt] kvm savevm/loadvm
by Serge Hallyn
Hi,
virsh has save/restore to do a one-time save+shutdown. But it
does not expose kvm's savevm/restorevm, which let's me do
incremental snapshots. Is there a specific reason why that
is not exposed in libvirt, or is it just that noone has
implemented it?
thanks,

[libvirt] [PATCH] lxc: Ensure to kill init process by sending SIGKILL if needed
by Ryota Ozaki
Init process may remain after sending SIGTERM for some reason.
For example, if original init program is used, it is definitely
not killed by SIGTERM.

[libvirt] [PATCH] Fix incorrect use of private data in remote driver
by Daniel P. Berrange
For upstream bug
https://bugzilla.redhat.com/show_bug.cgi?id=576796
The remote driver is using the wrong privateData field in
a couple of functions. THis is harmless for stateful
drivers like QEMU/UML/LXC, but will crash with Xen

[libvirt] [PATCH (v2)] Fix PCI address assignment if no IDE controller is present
by Daniel P. Berrange
The previous patch was flawed because it forgot to take into
account pre-reserved addresses
The PCI slot 1 must be reserved at all times, since PIIX3 is
always present, even if no IDE device is in use for guest disks
