[RFC PATCH v1 06/34] KVM: x86: mmu: add support for EPT switching
From: Marian Rotariu <marian.c.rotariu at gmail.com>
The introspection tool uses this function to check the hardware support
for EPT switching, which can be used either to singlestep vCPUs
on a unprotected EPT view or to use #VE in order to avoid filter out
VM-exits caused by EPT violations.

changing clock on host temporarily blocks guest OS operation
I have the following running on my system:
- one linux host running libvirt 1.2.20
- two Linux guestOS VMs running
When I change the clock on the host, the VMs stop responding: The VNC
connection stops working, the console connection to the VMs does not work,
ping stops reponding, libvirt commands temporarily stop working (after
issuing the command, the system just hangs).
I get control

removing virbr0
I am building a custom Linux image which includes KVM and will be installed
on multiple machines. By default when installing libvirt you get a 'default
network' which adds a 'vrbr0'.
I found several tutorials online about removing this 'virbr0' but I would
like to not have it in the first place.
I am compiling libvirt from source so I would think there is some compile

create a directory storage pool in a random location
Hi all,
I am trying to figure out if you can store the definition of a directory
storage pool in a custom location.
This is how I create the storage pool:
xmlDesc = """
<pool type='dir'>
<name>guest_images_storage_pool</name>
<uuid>8c79f996-cb2a-d24d-9822-ac7547ab2d01</uuid>

executing libvirt commands as a different user
I am using the libvirt API to manage VMs on the system, using a python
wrapper to execute commands.
I need to allow a webserver to access these commands and mostly read
information about the VMs. The problem is that when using the web interface
you use are basically running the commands as different user. Since
libvirtd is run as root by default you get permission errors.
Is there any way of

problem connecting to libvirtd remotely; compiled from sources
I am trying to add libvirt to a linux machine running a custom built linux-
there is no packet manager, everything is compiled using buildroot.
On this VM server, I am running libvirt-1.2.2 and the linux kernel is
3.18.21
Libvirtd starts and runs in the background. I can add/edit VMs using
Virt-install.
If I try to connect to the local qemu, everything works: virsh -c

libvirt list --all shows empty list after restart
Hi all,
I think I might have a small configuration issue: after restarting my
machine, all the VMs previously installed are not available.
virsh list --all shows an empty list.
The .img files where the VMs were intalled are present in the folder I put
them in. Furthermore if I import the VMs (virt-install -import) it all
seems to work. It's just that I don't want to have to do this

Re: libvirt domain configuration xml
Tanks for the reply Eric.
The only reason I'm not going through the API is because there is nothing
in the API (AFIK), that will allow you to modify the VNC settings, i.e.
enable/disable, change port number. So I figured, the only way to do it is
to modify the XML.
I can't use virsh edit because I need this whole behavior scripted.
So now if I want to change the VNC settings it

generate interface MAC addresses in a particular order
Hi all,
I am using libvirt to manage VM on my system; after creating a VM (default
no NICs are present in the configuration) you can add any number of
interfaces to it (as long as they exist on the host).
To do that, I edit the configuration xlm:
vmXml = self.domain.XMLDesc()
root = ET.fromstring(vmXml)
devices = root.find('./devices')

remove cdrom after installing os on a guest
Hi all,
I have the following issue, and I hope someone know a way to handle it.
I need to grammatically need to create/install a guest OS using the
libvirt API.
Currently what I do:
1. create a xml with the vm configuration (this will include a path to the
iso image)
2. connection.defineXML(<my_config>)
3. vm = connection.lookupByName(<domain_name>)
4. vm.create()
This will

Re: problem with disk virtio driver
Hi all,
I have to admit Martin might have been right: I upgraded to qemu 2.6.0
and still I see the same problem with virtio disks on my custom built Linux
box.
I create domain using the previously mentioned domain xml definition and
try to install ubuntu from an iso. Earty on during the installation I get
an error:

libvirt domain configuration xml
I am trying to change a domain configuration from a python script. More
specific, I want to edit the VNC settings. You can't do this using the
libvirt API so you have to edit the domain configuration:
Fo exmple, to disable VNC for a domain 'test1':
vmXml = vm.XMLDesc(0)
root = ET.fromstring(vmXml)
devices = root.find('./devices')
graphics = devices.find('graphics')

migrate a guest from VMware to KVM
I am trying to migrate a VMware guest to KVM. I have the .vmdk file which I
convert to qcow2 format using qemu-img convert.
The next step is to import the new img file.
If I use virt-install --import <guest config options> it all works fine.
But when I try the same think using the libvirt API I get the "no boot disk
found" message when starting the vm.

starting a domain only when you have enough resources
Hi all,
I am running KVM on a 3.18 kernel. The system runs and Atom processor with
2Gb RAM.
Using KVM you obviously can over allocate your resources: say you have 4
guests each configured with 1GB ram. Running all four at the same time,
depending on the workload, can crash the system - I get a kernel trace when
this happens.
But let's consider a simpler case: one guest with 1.5 Gb RAM,
