[libvirt] why is network i/o always zero?
by 黄亮
hi all
I'm using Xen on CentOS.I wanna monitor the network activity of a domain. When I use Domain.InterfaceStats( ... ), which is the C# binding of virDomainInterfaceStats, it returns -1.
I wonder if the function is not supported by Xen. So I using "domifstat", and I get
vif1.0 rx_bytes 0
vif1.0 rx_packets 0
vif1.0 rx_errs 0
vif1.0 rx_drop 0
vif1.0 tx_bytes 0
vif1.0 tx_packets 0
vif1.0 tx_errs 0
vif1.0 tx_drop 0
but it never change even when I use that domain to ping another.
virsh version:
Compiled against library: libvir 0.8.4
Using library: libvir 0.8.4
Using API: Xen 3.0.1
Running hypervisor: Xen 3.3.0
My question is, is Xen not support virDomainInterfaceStats or is somewhere I've gone wrong, that I can't get the network i/o statistics?
Thank you !

[libvirt] [PATCH] Don't generate cookies with v2 migration protocol.
by Daniel P. Berrange
The v2 migration protocol had a limit on cookie length that was
too small to be useful for QEMU. Avoid generating cookies with
v2 protocol, so that old libvirtd can still reliably migrate a
guest to new libvirtd uses v2 protocol.

[libvirt] inquiry, get native capabilities of the host
by Dong-In David Kang
Hello,
I'm interested in getting native capabilities of host CPU using libvirt.
I've looked at .../src/cpu/cpu_map.xml.
And it does describe native capabilities of host CPU very well.
But, libvirt always returns a subset of the native capabilities which is far different from the feature lists in the xml file.
(I'm testing with <model name='Westmere'>.)
The sponsor of my project is interested is high-performance computing.
And knowing native feature of the host CPU that can also be available to a virtual machine is very important for performance reason.
I couldn't find how to get the native features of the host that is described in .../src/cpu/cpu_map.xml.
Is there a way or libvirt API to get the native capabilities of host CPU that is well described in .../src/cpu/cpu_map.xml?
Thanks,
David.

[libvirt] [PATCH] Ensure p2p and direct migration use the new v3 protocol if available

The internal virDomainMigratePeer2Peer and virDomainMigrateDirect
helper methods were not checking whether the target supports the
v3 migration protocol.

[libvirt] [PATCH 0/7] round out persistent cpu.shares patches
by Eric Blake
When I pushed Hu's patch series this morning, I pointed out that
it was incomplete. This should fill in the gaps.
Eric Blake (7):
libvirt.h: consolidate typed parameter handling
remote: consolidate typed parameter handling
sched: introduce virDomainGetSchedulerParametersFlags
qemu: introduce qemuGetSchedulerParametersFlags
remote: introduce remoteGetSchedulerParametersFlags
virsh: improve schedinfo querying ability
sched: provide new API shims for remaining drivers

[libvirt] [PATCH] Fix messages using VIR_ERR_XML_ERROR
by Cole Robinson
This error code has existed since the dawn of time, yet the messages it
generates are almost universally busted. Here's a small sampling:
src/conf/domain_conf.c:4889 : XML description for missing root element is not well formed or invalid
src/conf/domain_conf.c:4951 : XML description for unknown device type is not well formed or invalid
src/conf/domain_conf.c:5460 : XML description for maximum vcpus must be an integer is not well formed or invalid
src/conf/domain_conf.c:5468 : XML description for invalid maxvcpus %(count)lu is not well formed or invalid
Fix up the error code to instead be
XML error: <msg>
Adjust the few locations that we using the original correctly (or shouldn't
have been using the error code at all).
