[libvirt] [PATCH] Disable IPv6 socket auto-binding to IPv4 socket
by Daniel P. Berrange
Sometimes getaddrinfo returns IPv4 addresses before IPv4 addresses.
IPv6 sockets default to attempting to bind to IPv4 addresses too.
So if the IPv4 address is activated first, then binding to IPv6
will fail.

[libvirt] Mounting a bare-metal folder as a drive
by Adam Mooz
Hello List,
Still working on getting the DVD drive to go, but I got another question. I'm attempting to ad a folder located on the bare-metal machine to the VM and have it appear as a drive (such as HDD), is this possible? I've looked over the documentation and it suggests this is only possible for USB devices or virtual disks, but not a folder.
How would I go about adding a folder located on the bare-metal to the VM to appear as a hard drive but still be accessable to the bare metal machine?

[libvirt] Possibly deadlock with tunnelled migration
by Cole Robinson
Hi Chris (and list),
Playing with TUNNELLED migration, I'm hitting an issue. Take this example:
VM URI = qemu+ssh://phys1/system
destconn = qemu:///system
invoking virDomainMigrate with a VM from the former URI, and destconn as the
latter, we will deadlock. The qemu driver would be reopening it's local
qemu:///system, and eventually lock up. We should probably add some sanity
checking for the URI we plan to open.
Aside from that, anyone have recommendations on the best way to handle the
above situation? I'm currently improving the migration support in
virt-manager, and if the TUNNELLED API requires opening a URI, it makes the
remote-to-local migration case a bit annoying, because we would have to
require the user to provide a remote accessible URI for the local system.
Thanks,
Cole

[libvirt] [PATCH] phyp: too much timeout when polling socket
by Eduardo Otubo
Hello all,
Since I moved to libssh2 I had noticed a weird behaviour, virsh was
taking too much time to complete the operations when using phyp driver.
Just found the problem, 10 seconds of timeout passed to select().
Changed to zero, since I'm just polling the socket.
Actually this patch is more important than it seems, now I can write a
script (using virsh) to test all the phyp features.
Thanks!
