[libvirt] snapshots += domain description?
by Philipp Hahn
Hello,
I just encountered a problem with the current snapshot implementation for
qemu/kvm: To revert back to a snapshot, the domain description must closely
match the domain description when the snapshot was created. If the ram-size
doesn't match or the VM now contains fewer CPUs or contains additional disks,
kvm will either not load the snapshot or the machine will be broken
afterwarts.
Is this a known problem?
Without looking into the implementation details I think saving the full domain
description instead of just a reference to the domain uuid as part of the
snapshot description would work better. Or am I supposed to save the domain
description myself in addition the the data saved
in /var/lib/libvirt/qemu/snapshot/$DOMAIN_NAME/$SNAPSHOT_NAME.xml. I think
this is very important feature, because when you - for example - notice that
you need additional disk space and would like to include an additional block
device, this is your ideal time to take a snapshot you can revert to when you
do something wrong.
Looking at VMware I see that reverting a VM there will not only revert the
disks and ram back to the saved state, but also the description including
name, ram size, etc.
Any comment or advise is appreciated.
Sincerely
Philipp Hahn

[libvirt] Is there smt missing at Java bindings?
by kadir yüceer
Hello all,
I've been posting questions about my issue to the user list but it seems
nobody can answer, so I had to try this list, sorry if there is any
disturbance.
Here is the case:
I've been trying to develop a java app that can register callbacks for
domain lifecycle events(suspend,resume,etc.). Only method that I've seen is
Connect.VirDomainEventRegisterAny, and there is an abstract callback method
inside VirConnectDomainEventGenericCallback. I implement the callback, and
register it for all the domains by passing the domain pointer as NULL.
Additionally for testing, I've added a println into the suspend function in
org.libvirt.Domain.java, and compiled the java bindings and used the new jar
file, and I was successful, I can see the message whenever I suspend the
domain either by clicking *pause* or by writing dom.suspend() in my java
app.
However, when I try to register a callback as I mentioned in the beginning
(with eventID 0, which is life_cycle ID), after the suspend operation, I get
the error that you can see at the end of the mail.
But before you check it out, I have to ask, are some of the event-related
features of libvirt missing in java bindings? For example;
VirEventAddHandleFunc, VirEventAddHandleCallback, and their derivatives. Is
this a problem or the only Connect.VirDomainEventRegisterAny method of java
binding suffice for providing callbacks for domain events?
Thanks in advance for your responses. The error is below.
Kind Regards
Kadir

[libvirt] [PATCH] qemu: Fix -chardev udp if parameters are omitted
by Cole Robinson
The following XML:
<serial type='udp'>
<source mode='connect' service='9999'/>
</serial>
is accepted by domain_conf.c but maps to the qemu command line:
-chardev udp,host=127.0.0.1,port=2222,localaddr=(null),localport=(null)
qemu can cope with everything omitting except the connection port, which
seems to also be the intent of domain_conf validation, so let's not
generate bogus command lines for that case.
Additionally, tweak the qemu cli parsing to handle omitted host parameters
for -serial udp

[libvirt] [BUG] Re: [2/6] loadvm: improve tests before bdrv_snapshot_goto()

This patch broke restoring not-running VMs using libvirt-0.8.7 with qemu-0.14:
When the domain is not running while taking a snpshot, the sn.vm_state_size
== 0:
2021 } else if (sn.vm_state_size == 0) {
(gdb) print sn
$6 = {id_str = "1", '\0' <repeats 126 times>, name = "pre-update-flash", '\0'
<repeats 239 times>, vm_state_size = 0, date_sec = 1302698007, date_nsec =
711909000,
vm_clock_nsec = 0}

Previously the qcow2 image was still reverted to the old state, so on the next
start of the domain the qcow2 image would be in the state of the snapshot

...

Now the qcow2 image is not reverted and when the domain is started, it is NOT
in the state of the snapshot.
I can't decide if this regression is an Qemu bug or libvirt should be adapted
to this new behavior.
I found the Bug also reported with Ubuntu and created a Bug in our own German
bugtracker:

[libvirt] [PATCH] freebsd: Fix build problem due to picking up the wrong libvirt.h
by Matthias Bolte
AM_GNU_GETTEXT calls AM_ICONV_LINK. AM_ICONV_LINK saves and alters
CPPFLAGS, but doesn't restore it when it finds libiconv. This
results in /usr/local/include ending up in the gcc command line
before the include path for the local include directory. This makes
gcc pick a previous installed libvirt.h instead of the correct one
from the source tree.
Workaround this problem by saving and restoring CPPFLAGS around
the AM_GNU_GETTEXT call.

[libvirt] Appending REJECT rules.
by Stephen O'Dor
Greetings folks,
I've patched the libvirt iptables interface to append it's REJECT
rules rather than insert at the head. Idea being that I'm not the only
person who usually puts the REJECTs at the end of a chain.
In my particular case any custom ACCEPT rules involving the bridge
interfaces would get pushed below the rules that libvirt puts in to
REJECT everything on the bridge interface.
I'm using the routed network mode, I have no idea if this hurts any
other network mode.
Thanks,
-Steve

[libvirt] [PATCH 0/2] Replace all remaining setgid calls with virSetUIDGID
by Jiri Denemark
Should we also ban setgid/setuid usage since we probably want to call
initgroups after them anyway?
Jiri Denemark (2):
util: Keep errno set to the root error after when returning from
virSetUIDGID
Replace all remaining setgid/setuid calls with virSetUIDGID
