[libvirt] [sandbox][PATCH] config: select specific kernel
by Radu Caragea
Added parameters to select a kernel through the release version and path to binary.
When setting kernel release version, the module search will be done in /lib/modules/<release>/kernel . Also, by default, after setting the kernel release version the default kernel image path will be /boot/vmlinuz-<release>
The two default to the running configuration: /lib/modules/`uname -r`/kernel and /boot/vmlinuz-`uname -r`
kver didn't seem suggestive enough; I used kernrelease and kernpath. To be changed if necessary.
Also removed utsname inclusion wherever it wasn't used at all anymore

[libvirt] [PATCH 0/5] Support forward mode='hostdev' and interface pools
by Shradha Shah
This patch series supports the forward mode='hostdev'. The functionality
of this mode is the same as interface type='hostdev' but with the added
benefit of using interface pools.
The patch series also contains a patch to support use of interface names
and PCI device addresses interchangeably in a network xml, and return
the appropriate one in actualDevice when networkAllocateActualDevice is
called. This functionality is not supported for any other forward mode
except hostdev.
Currently this patch series also does not support USB hostdev
passthrough.
At the top level managed attribute can be specified for a pf dev or an
interface dev (with identical results as when it's specified for a
hostdev
Shradha Shah (5):
Code to return interface name or pci_addr of the VF in actualDevice
Moved the code to create implicit interface pool from PF to a new
function
Introduce forward mode='hostdev' for network XML in order to use the
functionality of interface pools.
Forward Mode Hostdev Implementation
Supporting managed option for forward devs when using HOSTDEV mode

[libvirt] [PATCHv2 0/3] openvz: allow for runtime quota updates
by Guido Günther
Hi,
attached patches allow to change disk quota at runtime. This can later be
extended to update network configuration as well.
The patch revealed a problem of the openvz driver in genral: the
openvzLoadDomains only reads the on disk configuration but doesn't check if
running domains have (non persistent) diverging values due to openvz calls
without the "--save" option but that's part of another patch.
Changes since last time:
* add virDomainFSIndexByName to libvirt_private.syms
* check for unallowed updates in openvzUpdateDevice
Cheers,
-- Guido
Guido Günther (3):
Introduce virDomainFSIndexByName
openvz: add persist parameter to openvzSetDiskQuota
openvz: wire up domainUpdateDeviceFlags

[libvirt] [libvirt-sandbox][PATCH] module lookup and rundir fix
by Radu C.
Hello,
I've been trying to get libvirt-sandbox working on my Gentoo box but I ran into some difficulties. The version I'm using is the latest git one.
The first problem was the following when running virt-sandbox:
"Unable to start sandbox: Error opening file '/tmp/libvirt-sandbox-9ivpRN/9pnet.ko': File exists"
I pinpointed the problem to the following diff in commit [05fb94d2c42abe9cfd86c3663d704c268f325503]:
- gchar *moddirpath = g_strdup_printf("/lib/modules/%s/kernel",
+ gchar *moddirpath = g_strdup_printf("/lib/modules/%s",
The problem is that symlinks are made to the build directory and it finds a module multiple times.
I inserted a printf in the lookup loop so here's what I mean:
dmns libvirt-sandbox # virt-sandbox -c qemu:///system -n test1323 -v
-d /usr/bin/yes
found: /lib/modules/3.4.0-gentoo/kernel/fs/fscache/fscache.ko

found: /lib/modules/3.4.0-gentoo/build/net/9p/9pnet_virtio.ko
The next problem was the following:
dmns libvirt-sandbox # virt-sandbox -c qemu:///system -n test123 -v -d
/usr/bin/yes
Unable to start sandbox: Failed to create domain: internal error
Process exited while reading console log output: char device
redirected to /dev/pts/1
char device redirected to /dev/pts/3
Virtio-9p Failed to initialize fs-driver with id:fsdev-fs1 and export
path:libvirt-sandbox/test123/config
It appears when running as root because of the following line:
./libvirt-sandbox/libvirt-sandbox-context.c: cachedir = (getuid() ? g_get_user_cache_dir() : RUNDIR);
RUNDIR is always "" due to being compiled with -DRUNDIR=\"\" . This is because there's a typo in makefile.am
Both of these are fixed in the diff attachment.
Having these fixes in place everything works fine when using libvirt 0.9.10 but for newer versions I noticed every time I ran virt-sandbox the libvirtd daemon would segfault.
Using git bisect I traced the problem back to commit [1]. So I reverted back to libvirt 0.9.10 but I believe there is a problem both in the commit and somewhere in libvirt-sandbox.
Please have a look and tell me if you need extra info.

Hi Pankaj,
Could you attach your virt-install.log as an attachment?
it locals in ~/.virtinst/virt-install.log.
Or Is it okay if you also upgrade your python-virtinst?
Thanks,
Alex

Subject: [libvirt] Error while installing a guest
Hi all ,
I have SL6.2 x86_64 Installed on my system
I updated libvirt version from 0.9.4 to 0.9.11, I had removed previous libvirt via yum
I done this by compiling the source.
I started libvirt daemon created by compiling source :
# ./root/libvirt_0.9.11/build/daomen/libvirtd
Now I tried to create a guest:-
[root@localhost libvirt-0.9.11]# /usr/sbin/virt-install --accelerate --hvm --connect qemu:///system --name g3 --vcpu=1 --ram 1024 --os-type=linux --os-variant=rhel6 --network bridge:br0 --disk /var/lib/libvirt/images/g2 --disk=/opt/SL-62-x86_64-2012-02-06-Install-DVD.iso,device=cdrom,perms=ro --location=/mnt/ --nographics --serial pty --extra-args=console=ttyS0,115200n8 --keymap=en --force
The command line above normally works fine (I have created many vm by using same above command)
But here Following error comes

Please check your guest image size by qemu-img info or ll -h, for
example: qemu-img info /var/lib/libvirt/images/g2,
and run 'ifconfig | grep br0' then paste output in here, thanks.
In addition, you may also use interactive virt-install to install a
guest with --prompt option then step by step.

[libvirt] [PATCH 0/2] Don't overwrite security labels
by Michal Privoznik
If we have a running domain A with a PCI/USB device X passthrough,
and user wants to start domain B with again device X, we
reject start however, call qemuProcessStop to perform rollback.
This however does not do any rollback just cleanup therefore
rewrite labels on device X leaving domain A in silly situation.

qemuProcessStop: Switch to flags
qemu: Don't overwrite security labels

[libvirt] [PATCH] virsh: let 'connect' without args remember -c option
by Eric Blake
If a user invokes 'virsh -c $URI', then within that batch shell,
they probably want 'connect' to revert to $URI rather than the
normal default URI you get for passing in NULL.
In particular, I had a setup where qemu:///session was failing,
but took 20 seconds to fail; since 'make -C tests check TESTS=virsh-all'
exercises the command 'virsh -c test:///default connect' without
arguments, it was locking up for 20 seconds trying to connect to
qemu, even though the testsuite specifically wants to limit itself
to the test:///default URI.
* tools/virsh.c (__vshControl): Add member.
(main, vshParseArgv): Set it.
(vshDeinit): Clean it up.
(cmdConnect): Use it to reopen to original connection.
---
This doesn't fix the root cause of this problem:
https://www.redhat.com/archives/libvir-list/2012-June/msg00237.html
but at least it makes my 'make check' runs faster while
I still investigate the root problem.
