[libvirt] [RFC PATCH 0/2] Add some systemtap probes to RPC code
by Daniel P. Berrange
Trying to investigate & debug the keepalive series I decided we
needed a better way to trace the RPC protocol than the regular
debug messages. Ideally we'd have a wireshark dissector but that
seems like it will be an awful lot of work todo. So instead I
have added a few systemtap probes to the RPC call which fire
everytime an RPC message is queued for dispatch, or a completed
RPC message is read off the wire
Now I can see all communications using a script like this
# cat > watch.stp <<EOF
function msginfo(prefix, prog, version, proc, type, status, serial)
{
if (type == 0)
typestr = "call"
else if (type == 1)
typestr = "reply"
else if (type == 2)
typestr = "message"
else if (type == 3)
typestr = "stream"
else
typestr = "unknown"
if (status == 0)
statusstr = "ok"
else if (status == 1)
statusstr = "error"
else if (status == 2)
statusstr = "continue"
else
statusstr = "unknown"
printf("%s program: %-10d version: %d procedure: %-4d type: %u:%-9s status: %u:%-9s serial: %-4d\n",
prefix, prog, version, proc, type, typestr, status, statusstr, serial);
}
probe libvirt.rpc.server_msg_rx {
msginfo(">S", prog, vers, proc, type, status, serial)
}
probe libvirt.rpc.server_msg_tx {
msginfo("<S", prog, vers, proc, type, status, serial)
}
probe libvirt.rpc.client_msg_rx {
msginfo("<C", prog, vers, proc, type, status, serial)
}
probe libvirt.rpc.client_msg_tx {
msginfo(">C", prog, vers, proc, type, status, serial)
}
EOF

Is the trace information resulting from 'virsh dominfo $VM'
An RPC call shoudl result in 4 messages, tx by client, rx
by server, tx by server and rx by client. An async event
will only result in 2 messages, tx by server, rx by client
and so on.
A further enhancement I want to make is to make the rpc
generator script, spit out a systemtap function for
converting procedure numbers into function/event names,
as well as adding helper functions for converting program
type and status numbers into friendly strings

[libvirt] [PATCH 1/1] [RFC] Parallels Server Bare Metal driver stub
by Dmitry Mishin
Parallels Server Bare Metal is a virtualization solution which allows to run
both Containers (OpenVZ-like) and virtual machines (like any other hardware
hypervisor).
This patch implements initial driver stub with almost no functionality except an
ability to open and close driver. At the same time it contains initialization of
Parallels API and clearly demonstrates supposed approach to future driver
implementation. In particular, I suppose to use parallels-virtualization-sdk
library provisioned with the PSBM distribution (and separately also) for PSBM's
virtual servers management.

[libvirt] [PATCH] qemu: Check for outstanding async job too
by Michal Privoznik
Currently, qemuDomainGetXMLDesc and qemudDomainGetInfo check for
outstanding synchronous job before (eventual) monitor entering.
However, there can be already async job set, e.g. migration.
