[libvirt] [PATCH 1/6] domMemoryStats: Add domainMemoryStats method to struct _virDriver
by Adam Litke
Set up the types for the domainMemoryStats function and insert it into the
virDriver structure definition. Because of static initializers, update every
driver and set the new field to NULL.
Note: The changes in python/* are to fix compiler errors. The actual python
binding is implemented in a later patch.

[libvirt] Executing scripts when bridge interface becomes available
by Felix Schwarz
Hi,
I'm using libvirt on a CentOS 5.4 host (so my libvirt is quite old) with a
routed setup. My configuration is easy and works reliable as far as I can tell
now.
As far as I know, I have to add routes manually (so that the host knows which
IPs need to be routed to the virbr1). My ip command looks like this:
/sbin/ip route add <guest ip> dev virbr1 scope link
Currently I have really problems finding the right spot where I should
configure the routes and it looks like libvirt does not offer any support for
that.
1. I can add the route when my network comes up because virbr1 is not
available at that time.
2. If I switch my vm to the 'ethernet' interface, I can use a custom script
but then I have to do all the network setup myself which looks like
overkill and time-consuming (as I have to rebuild things that libvirt
already does perfectly). I just want to add some routes...
To me the perfect solution would be either:
a) have start/stop scripts defined in the network configuration
b) have start/stop scripts defined in the vm configuration
- Does libvirt 0.7 offer things like that? (I could not find something in the
documentation)
- Is there an obvious way that I missed when it comes to route configuration?

Re: [libvirt] New libvirt API for domain memory statistics reporting (V4)

Okidoc, done !
There was a bit of tweaking since this conflicted with another new API,
but this was eay to solve. I double checked the new
src/remote/remote_protocol.x description and that looks fine,
I think the only thing missing is a description of the new virsh command
in tools/virsh.pod and I think this will be complete. Ah and other
bindings need to be updated to export the new function, but that's
seaparate.
thanks !

[libvirt] [PATCH] Fix compilation with gcrypt < 1.4.2
by Matthias Bolte
Commit 33a198c1f6a4a1bc7f34d50a31032e03bec10fee increased the gcrypt
version requirement to 1.4.2 because the GCRY_THREAD_OPTION_VERSION
define was added in this version.
The configure script doesn't check for the gcrypt version. To support
gcrypt versions < 1.4.2 change the virTLSThreadImpl initialization
to use GCRY_THREAD_OPTION_VERSION only if it's defined.

With the previous logic, if libhal_get_all_devices function was not found,
HAVE_HAL would be defined for the preprocessor but it wouldn't be enabled

Thank you for your advice.
And I compiled the libvirt-0.7.4 again
./configure
make
make install
After reboot the machine, I run the binary virsh, the result is as below:
[root@kvm bin]#virsh
error: unable to connect to '/usr/local/var/run/libvirt/libvirt-sock': No such file or directory
error: failed to connect to the hypervisor
Then I run the virsh -c ,the result is as below:
[root@kvm bin]#virsh -c qemu+unix:///system?socket=/var/run/libvirt/libvirt-sock
error: unable to connect to '/var/run/libvirt/libvirt-sock': No such file or directory
error: failed to connect to the hypervisor
At the same time, I found the libvird didn't running, I don't know whether this caused the error or not.
I don't know why this error occurs.
Maybe the reason is the libvirt didn't support the use kvm virtualization on ia64 as berrange said before.
But I modify the qemu_conf.c and add ia64 information into the struct arch_info_hvm.
Then compiled again. The errors remain.
Please forgive my poor program skills, I can't add the ia64 into the libvirt kvm supports.
Will you want to do some works on this?
Thanks a lot.

[libvirt] [PATCH] Fix reporting of TLS connection errors
by Daniel P. Berrange
The code for connecting to a server tries each socket in turn
until it finds one that connects. Unfortunately for TLS sockets
if it connected, but failed TLS handshake it would treat that
as a failure to connect, and try the next socket. This is bad,
it should have reported the TLS failure immediately.
$ virsh -c qemu://somehost.com/system
error: unable to connect to libvirtd at 'somehost.com': Invalid argument
error: failed to connect to the hypervisor
$ ./tools/virsh -c qemu://somehost.com/system
error: server certificate failed validation: The certificate hasn't got a known issuer.
error: failed to connect to the hypervisor
* src/remote/remote_driver.c: Stop trying to connect if the
TLS handshake fails
