[Libvir] Proposal: More script hooks for <interface type='ethernet'>
by Charles Duffy
I have a few issues with <interface type='ethernet'>:
- The requirement that either
(1) the tap device already exists and has a constant name, or
(2) the tap device can be created by the current user without
privilege escalation
doesn't work for places where the user wants to
- dynamically generate tap devices
- ...but is running kvm without privileges to do so.
(this is particularly likely now that write privileges to
/dev/net/tap are not enough, and the user needs CAP_NET_ADMIN to
create a tap device).
Allowing a target script to be specified (which is responsible for
gaining any privileges necessary) which runs *before* the tap device
is opened and would resolve this.
- A qemu-ifup script can be specified, but not a qemu-ifdown
replacement.
Before looking to use libvirt, I had kvm's invocation wrapped by a
script which did appropriate privilege escalation (ifname=$(sudo tunctl
-b -u $USER), with sudo configured with the NOPASSWORD flag for this
request -- though plenty of other approaches are certainly possible). It
would be ideal if more hooks were available... for instance:
<interface type='ethernet'>
<!-- script gives device name on stdout -->
<target script='/usr/local/bin/make-me-a-tap-device'/>
<!-- preexisting argument and syntax for up scripts -->
<script path='/etc/qemu-ifup-mynet'/>
<!-- option to specify a down script, passed to qemu via
'downscript=' parameter-->
<script-down path='/etc/qemu-ifdown-mynet'/>
</interface>
Working around this means that I would need to preallocate the tap
devices and assign them to specific VMs (boo! hiss!) or that (if I
wrapped libvirt's invocation to have the tap device created just ahead
of time and its name substituted into interface/@dev) 3rd-party
libvirt-based management tools couldn't be used (which would defeat the
point of switching to libvirt from my homegrown script collection in the
first place).
So -- does the proposed syntax extension look reasonable?

[Libvir] Libparted history contribution
by Matt Davis
Hello,
I am sending this email out to various programs that use libparted for partition
table manipulation. If you are on the libparted devel list, you probably have
caught word of this. I have implemented some functionality that allows parted
to maintain a list of disk changes, allowing for a user to undo/redo changes
before they are actually committed, or written, to disk. This "History" is a
safety feature, and a library change vs usefulness might not be wanted by you
all. I was just querying to see if such functionality, as an addition to
libparted, would be welcomed? In any case, it might be useful for me to wrap it
up into its own library, possibly something such as libparted-utilities or
extras.
While the changes I have implemented can exist outside of the library, I figured
it might be something other projects might find useful. But making any library
changes, especially when many well-known projects use such a library, is a
serious decision. If this is a worthy change I would like to hear your
feedback.
Thanks

[Libvir] Why QEMU?
by Anton Protopopov
Hi, all.
When I executing virsh to connect to openvz I get the following:
[root@localhost ~]# virsh -c openvz:///system
libvir: QEMU error : cannot create bridge 'virbr0' : File exists
Failed to autostart network 'default': cannot create bridge 'virbr0' :
File existsWelcome to virsh, the virtualization interactive terminal.
Type: 'help' for help with commands
'quit' to quit
virsh #

But I didn't want to connect to QEMU...

[Libvir] [RFC][PATCH]: Make the iscsi storage backend mostly use sysfs
by Chris Lalancette
Hello,
The newer version of iscsi-initiator-utils (6.2.0.865-0.2),
available in the f8-updates repository, is required as part of the fix
for a hang when doing iscsi logout (the other fix is in the 2.6.25
kernel). Unfortunately, this version also changes the output of the
iscsiadm -m session -P 3 command; this output was being used to gather
the scsi devices available in a pool and present them as volumes.
Consequently, when starting an iSCSI pool on a machine with these newer
versions of the iscsi tools, the pool will be successfully created but
you won't be able to see any of the LUNs presented.
The attached patch *lessens* our dependency on the iscsiadm output by
using sysfs to gather the /dev devices. Note that this patch is not to
be applied; I'm just putting it out there so people can take a look at
it. DanB has suggested getting rid of our dependency on the iscsiadm
output altogether is the way to go, and I agree with him there; this is
mostly just a short-term solution, to possibly base future work on.

[Libvir] Problem using libvirtd on RHEL5.1
by Tiago Cruz
Hello 8-)
I'm using libvirt-0.4.0-1 (re)compiled from libvirt-0.4.0.tar.gz, on Red
Hat EL 5.1 x86_64.
The problem is:
# /etc/init.d/libvirtd start
Starting libvirtd daemon: libvir: QEMU error : cannot create bridge 'virbr0' : File exists
Failed to autostart network 'default': cannot create bridge[FAILED]' : File exists
And I can't destroy the 'virbr0', because I don't know how :^)
---
I've tried do compile the libvirt-cvs-snapshot.tar.gz, but I can't
too :(
In file included from libvirt.c:36:
util.h:28:22: error: util-lib.h: No such file or directory
RPM build errors:
File not found: /var/tmp/libvirt-0.4.0-root/usr/libexec/libvirt_parthelper
Maybe you have some tip/ trick for me :)
Many thanks

[Libvir] tons of format string warnings on rawhide
by Jim Meyering
Avoid warnings like this:
file:nnn:format not a string literal and no format arguments
Easy to fix: prepend an "%s" argument.

[Libvir] [PATCH] 2/2: Use safewrite in place of write, in many cases.
by Jim Meyering
Use safewrite in place of write, in many cases.
Also add "make syntax-check" rules to ensure no new uses sneak in.
There are many uses of write like this:
if (write (fd, xml, towrite) != towrite)
return -1;
The problem is that the syscall can succeed, yet write less than
the requested number of bytes, so the caller should retry
rather than simply failing.
This patch changes most of them to use util.c's safewrite wrapper,
which encapsulates the process. Also, there were a few cases in
which the retry loop was open-coded, and I replaced those, too.
Note: the change to libvirt_proxy.c removes a diagnostic that
would have warned about an EINTR-interrupted (and retried) write,
but that seems ok.
* Makefile.maint (sc_avoid_write): New rule, to avoid recurrence.
* .x-sc_avoid_write: New file. Record two legitimate exemptions.
* qemud/qemud.c (sig_handler, qemudClientWriteBuf): Use safewrite, not write.
* src/conf.c (__virConfWriteFile): Likewise.
* src/qemu_conf.c (qemudSaveConfig, qemudSaveNetworkConfig): Likewise.
* src/qemu_driver.c (qemudWaitForMonitor, qemudStartVMDaemon)
(qemudVMData, PROC_IP_FORWARD): Likewise.
* proxy/libvirt_proxy.c: Include "util.h".
(proxyWriteClientSocket): Use safewrite.
* src/test.c (testDomainSave, testDomainCoreDump): Likewise.
* src/proxy_internal.c (virProxyWriteClientSocket): Likewise.
* src/virsh.c: Include "util-lib.h".
(vshOutputLogFile): Use safewrite.
* src/console.c: Include "util-lib.h".
(vshRunConsole): Use safewrite.

[Libvir] [PATCH] write(2) may write less than the total requested
by Jim Meyering
Use safewrite in place of write, in many cases.
And add "make syntax-check" rules to ensure no new uses sneak in.
There are many uses of write like this:
if (write (fd, xml, towrite) != towrite)
return -1;
The problem is that the syscall can succeed, yet write less than
the requested number of bytes, so the caller should retry
rather than simply failing.
This patch changes most of them to use util.c's safewrite wrapper,
which encapsulates the process. Also, there were a few cases in
which the retry loop was open-coded, and I replaced those, too.
However, there remain invalid uses of write in both virsh.c and
console.c. I would have replaced those, too, but util.c isn't
linked with them, so it would have made this change more involved.
xend_internal.c has one use, but it's ok, and not easily replaced.
Note: the change to libvirt_proxy.c removes a diagnostic that
would have warned about an EINTR-interrupted (and retried) write,
but that seems ok.

[Libvir] Please add RSS for libvirt updates.
by Atsushi SAKAI
Hi,
I have a request about libvirt updates.
Currently I am checking software updates by seeing
RSS reader.
Of course,
mercurial(hg) and git creates RSS feeds.
But CVS does not create such kind of feeds.
I hope some day libvirt adds RSS feeds
by using cvs2rss etc.
http://laughingmeme.org/cvs2rss/
Thanks
