[libvirt] [PATCH] Initialize vm def monitor fd
by Cole Robinson 17 Feb '09

17 Feb '09

We weren't properly initializing the monitor fd value in the VM definition structure. If qemu failed to start up, this could lead to closing stdin, which made all sorts of poo hit the fan. The attached patch fixes this. Thanks, Cole

[libvirt] [PATCH] Detect bridge name collisions when defining a virtual network
by Cole Robinson 17 Feb '09

17 Feb '09

The attached patch is a partial fix for rhbz 479622. If a virtual network is defined with an explicit bridge name, make sure it doesn't collide with other virtual network bridge names. Thanks, Cole

[libvirt] Network Configuration question
by Remko Nolten 17 Feb '09

17 Feb '09

Hi! For a shared virtual hosting project with some friends we need a pretty specialized network configuration. Because we have virtually no time for experimenting (no pun intended), and the hosting organization has no experience with libvirt/KVM configurations they suggested to try and ask here. So, this is the situation: We have a server with one physical connection. Each user gets one virtual machine with its own IP-address (we have our own ip-range). The hosting organization gives us one "main" address 'A' with netmask 255.255.255.0 (/24) and a default gateway for our host machine. Besides this we get a number of addresses B1, B2, etc. with netmask 255.255.255.255 (/32) and without a default gateway. The switch just routes the traffic to our server for each ip-address we own (A and Bn). According to our hosting organization, the normal solution is to configure a loopback interface for each of the ip-addresses on the server so you can configure your software just to use one of the addresses. But we are not sure how this will work out in our virtual environment. Our intuition tells us we need to use the routing network forwarding mode, but when we bring the server to the data center we don't want to have any surprises. :) Here at home I don't have to possibility to create similar circumstances as in the data center due to some restriction from my ISP, so I hope someone can tell me if our intuition is correct or that we need to use some other method. Thanks in advance! -- Remko Nolten Tel: 06-45600767 E-mail: remko(a)nolten.nu

[libvirt] [PATCH] Don't check volume format for lvm backing store
by Cole Robinson 16 Feb '09

16 Feb '09

With the recently added COW support, we were trying to validate the passed logical volume's format, when there won't ever be one pulled from the xml (logical volumes don't have any valid format values). Just remove this check, and let any validation in this manner be done by the actual call to 'lvcreate'. Thanks, Cole

[libvirt] [PATCH] Fix generating python bindings
by Cole Robinson 16 Feb '09

16 Feb '09

The recent API additions virSaveLastError and virFreeError upset the python bindings generator. Add a rule to explicitly skip them for the bindings, since (as far as I can tell) the libvirtError class provides everything we need. Thanks, Cole

[libvirt] [PATCH] Fix virsh {net,pool}-edit
by Cole Robinson 16 Feb '09

16 Feb '09

The dumpxml commands for networks and pools don't support any flag arguments, and in fact explictly fail if flags != 0. This is not the case for vm dumpxml though, and flags were added to the base 'edit' implementation in virsh recently. The net and pool derivatives were not addressing this difference, so any net-edit or pool-edit attempt currently gives an error like: Network error : invalid argument in virNetworkGetXMLDesc The attached patch is one way to fix this. Thanks to Charles Duffy for the report. - Cole

[libvirt] Per-VM access control
by Jan Kasprzak 16 Feb '09

16 Feb '09

Hello, is it possible to run libvirt as a "hosting-like" environment? we would like to provide virtual machines for our users, but we would like them to be able to reset/reboot/poweroff only their own VMs, connect to the serial console of their own VMs only, and even maybe connect to the graphical console of their own VMs. Is it possible with libvirt, and without giving them shell access to the hosting machine? For the serial console, I thought about creating a ssh-only account with hardcoded "virsh console <their_machine_name>" command, but "virsh console" can be escaped from using ^], so this is not secure - this way they would be able to get access to other VMs as well.
