Currently we are unable to properly run guestfsd (the daemon) under valgrind. Attempts to run valgrind inside the appliance have not been successful (see patch 1/7). However we desperately need better valgrind coverage of the daemon, particularly because it is doing a lot of complex parsing of program output. This has been a problem for a long time. A better way to attack this problem is to run the daemon as a regular host process and connect libguestfs...

As suggested by Bjorn, I added a small virtio-entropy based sample. It is a very bare-bones clone of virtio-rng.c that only sends a single request.

...his adds support for vhost-net virtio kernel backend. This patch is not intended to being merged yet. I'm posting it for the benefit of people testing the backend. Usage instructions: vhost currently requires MSI-X support in guest virtio. This means guests kernel version should be >= 2.6.31. To enable vhost, simply add ",vhost" flag to nic options. Example with tap backend: qemu-system-x86_64 -m 1G disk-c.qcow2 \ -net tap,ifname=msttap0,script=/home/mst/ifup,downscript=no \ -net nic,model=virtio,vhost Example with raw socket backend: ifconfig eth3 promisc qemu-system-x86_...
