libguestfs on Debian 6 squeeze problems
by Zoltan
I'm trying to install libguestfs on Debian squeeze installed from
http://people.debian.org/~bengen/libguestfs/
It does not work. Here are the details:
I was able to install libguestfs-tools and its dependencies. However,
aptitude removed the following two packages: qemu and qemu-system. I'm
not sure if it's okay or not. If I try to install those packages back, I
get the following:
# aptitude install qemu qemu-system
The following NEW packages will be installed:
qemu qemu-system{b}
0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 16.6 MB of archives. After unpacking 50.9 MB will be used.
The following packages have unmet dependencies:
qemu-system: Depends: openbios-ppc (>= 1.0+svn1018) but 1.0+svn640-1
is installed.
Depends: openbios-sparc (>= 1.0+svn1018) but
1.0+svn640-1 is installed.
My first question is, is this normal? Do I need the qemu and qemu-system
packages installed? What about these openbios dependencies?
The next problem I have encountered: When I installed libguestfs-tools,
aptitude also installed the cryptsetup ( cryptsetup/squeeze uptodate
2:1.1.3-4squeeze2 ) package as a dependency. Since then, every time I
run update-initramfs, I get this:
# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-2.6.32-5-amd64
cryptsetup: WARNING: failed to detect canonical device of /dev/md1
cryptsetup: WARNING: could not determine root device from /etc/fstab
I use RAID1 arrays md1 and md3 on my system. I googled "cryptsetup:
WARNING: failed to detect canonical device" and "cryptsetup: WARNING:
could not determine root device" to no avail. I mean, some other people
get these warnings too, but I haven't find any solution to get rid of
these warning messages. Since these are just warnings, I guess I can
just ignore these?
Now, back to the main issue: libguestfs does not work! When I run
libguestfs-test-tool, it stops with the following error:
Failed to connect to virtio-serial channel.
This is a fatal error and the appliance will now exit.
Usually this error is caused by either QEMU or the appliance
kernel not supporting the vmchannel method that the
libguestfs library chose to use. Please run
'libguestfs-test-tool' and provide the complete, unedited
output to the libguestfs developers, either in a bug report
or on the libguestfs redhat com mailing list.
When I try to use the virt-filesystems tool, after about 2-3 seconds it
stops with an error message that says:
# virt-filesystems -a myimagefile.img
libguestfs: error: guestfs_launch failed, see earlier error messages
Then in the log files I see these:
libvirtd: 04:49:11.561: warning : qemudStartup:1832 : Unable to create
cgroup for driver: No such device or address
libvirtd: 04:49:11.729: warning : lxcStartup:1900 : Unable to create
cgroup for driver: No such device or address
Basically, none of the libguestfs tools work on my Debian squeeze
system... What can I do to make libguestfs install properly?
I thought that maybe I should install a newer Linux kernel from
backports? Currently I use the following squeeze kernel:
linux-image-2.6.32-5-amd64/squeeze uptodate 2.6.32-45
Do I need to install 3.x kernel for libguestfs ?
BTW, the following packages are installed from the squeeze-backports (or
Bengen's) repository on my system:
febootstrap/squeeze uptodate 3.14-2~bpo60+1
ipxe/squeeze uptodate 1.0.0+git-2.149b50-1~bpo60+1
kvm/squeeze uptodate 1:0.14.1+dfsg-4~bpo60+1
libguestfs0/squeeze uptodate 1:1.16.17-1~bpo60+1
libguestfs-perl/squeeze uptodate 1:1.16.17-1~bpo60+1
libguestfs-tools/squeeze uptodate 1:1.16.17-1~bpo60+1
qemu-keymaps/squeeze uptodate 0.14.1+dfsg-3~bpo60+1
qemu-kvm/squeeze uptodate 0.14.1+dfsg-4~bpo60+1
qemu-user/squeeze uptodate 0.14.1+dfsg-3~bpo60+1
qemu-utils/squeeze uptodate 0.14.1+dfsg-3~bpo60+1
seabios/squeeze uptodate 1.6.3-2~bpo60+1
vgabios/squeeze uptodate 0.7a-1~bpo60+1
Do I miss something?
I would really appreciate if someone can point me to the right
direction! Thanks!

BTW, another problem about mount:

failure to find hostname causing fatal error
by Todd Mummert
Trying to inspect an old OpenSuSE image, which has an empty
/etc/HOSTNAME file. This causes check_hostname_unix() in
inspect_fs_unix() to return -1 -- causing inspection to fail.
Somewhat interestingly, if no files of interest were found, the
function would return 0.....which I think doesn't cause problems
upstream.
It's somewhat related to this closed bug where the fix was to set the
return code to 0 and hostname could end up null.
https://bugzilla.redhat.com/show_bug.cgi?id=726739
It may be correct, in fact, to try each of the hostname checks until 1
succeeds or they all fail, and then return 0 in all cases.

Notes on libguestfs on Fedora/ARM
by Richard W.M. Jones
I've added some commits to ensure libguestfs can compile on Fedora/ARM
(with all options and bindings enabled except Haskell).
However it doesn't quite run yet:
(1) The Fedora qemu package is broken. Don't use it; compile qemu
from source instead.
(2) You have to configure libguestfs to pass extra qemu options.
Currently you should use:
PATH=/path/to/your/qemu/arm-softmmu:$PATH \
./autogen.sh \
--with-qemu=qemu-system-arm \
--with-qemu-options="-M versatilepb -cpu arm926"
(3) The versatilepb emulated system only supports memory < 512MB, and
will only boot the standard kernel, so when running you need something
like this:
FEBOOTSTRAP_KERNEL=/boot/vmlinuz-3.3.4-4.fc17.armv7hl \
FEBOOTSTRAP_MODULES=/lib/modules/3.3.4-4.fc17.armv7hl \
LIBGUESTFS_MEMSIZE=256 \
LIBGUESTFS_DEBUG=1 \
make check
(4) Currently this will fail because the virtio-pci driver doesn't
work on ARM. The characteristic stack trace starts with:
[ 4.841052] [<c0230a08>] (vp_reset+0x14/0x64) from [<c022fa48>] (register_virtio_device+0x4c/0x94)
[ 4.844047] [<c022fa48>] (register_virtio_device+0x4c/0x94) from [<c04277bc>] (virtio_pci_probe+0x100/0x168)
[ 4.846966] [<c04277bc>] (virtio_pci_probe+0x100/0x168) from [<c02138e0>] (pci_device_probe+0x90/0x120)
[ 4.850258] [<c02138e0>] (pci_device_probe+0x90/0x120) from [<c025fe98>] (driver_probe_device+0x148/0x2c4)
(Note that you cannot work around this by choosing a different block
driver, because eventually virtio-serial is required which will fail
in the same way).
(5) To fix (4), it is planned to move to vexpress emulation. This
also lifts the memory limit to <= 2GB. vexpress doesn't have PCI at
all, but it has a non-upstream virtio-mmio transport which allegedly
works (I've not tried it). This also requires a new kernel for
Fedora/ARM build with vexpress support. The configure options
mentioned in step (2) will change to:
--with-qemu-options="-M vexpress-a9 -cpu cortex-a9"
