SDL display of HVMs -- how?
I''m having some trouble working out how to make the SDL interface
for HVM domUs appear. The documentation simply says "it will appear"
when you start the domU, but doesn''t state what packages or libraries
are needed in order for this magic to happen, or explain how to debug
it if it doesn''t happen. All that I''m getting at the moment is a domU

New btrfs-progs integration branch
I''ve just pushed out a new integration branch to my git repo. This
is purely bugfix patches -- there are no new features in this issue of
the integration branch. I''ve got a stack of about a dozen more patches
with new features in them still to go. I''ll be working on those
tomorrow. As always, there''s minimal testing involved here, but it
does at least compile on

The state of btrfs RAID6 as of kernel 3.13-rc1
Hi
What is the general state of btrfs RAID6 as of kernel 3.13-rc1 and the
latest btrfs tools?
More specifically:
- Is it able to correct errors during scrubs?
- Is it able to transparently handle disk failures without downtime?
- Is it possible to convert btrfs RAID10 to RAID6 without recreating the fs?
- Is it possible to add/remove drives to a RAID6 array?
Regards,
Hans-Kristian

Metadata size
I''m a little concerned about the size of my metadata. I''m doing
raid10 on both data and metadata, and:
hrm@vlad:mnt $ sudo btrfs fi df /mnt
Data: total=488.01GB, used=487.23GB
Metadata: total=3.01GB, used=677.73MB
System: total=11.88MB, used=52.00KB
hrm@vlad:mnt $ find /mnt | wc -l
20137
By my calculations, that''s something on the order of 17.5K per

Btrfs questions
i am looking at using btrfs for a new project and i have a few questions:
* i have heard that as it currently stands Btrfs has some issues to be used as a Lustre file system; is he aware of the issues and any plans to address these and integrate Btrfs in to Lustre
* any plans to support native clustering on Btrfs
* on ZFS the ZIL is a separate device, any plans to implement a the

Two identical copies of an image mounted result in changes to both images if only one is modified
Hi,
I''ve observed a rather strange behaviour while trying to mount two
identical copies of the same image to different mount points.
Each modification to one image is also performed in the second one.
Example:
dd if=/dev/sda? of=image1 bs=1M
cp image1 image2
mount -o loop image1 m1
mount -o loop image2 m2
touch m2/hello
ls -la m1 //will now also include a file calles "hello"

Bug in mkfs.btrfs?!
Hi,
I wanted to create a new btrfs fs for my backups.
When trying to mkfs.btrfs for that device, I''m getting
"error checking /dev/loop2 mount status"
With strace I see where the problem is:
lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par",
0x7fffa30b3cf0) = -1 ENOENT (No such file or directory)
The problem is there is something missing

pxelinux bootup problems on EPIA-M
Hi,
I was wondering if anyone had a good dhcpd.conf and /tftpboot
files for a EPIA-M motherboard with RedHat 9.0.... Or maybe
just a configuration that works with the EPIA-M (doesn't matter
which type of linux).
I'm trying to boot the system from the network and it seems to
be getting to downloading pxelinux.0 but then nothing happens
after that....
I'm using ISC dhcpd V3.0pl2,

How does btrfs behave on checksum mismatch?
I came across the tidbit that ZFS has a contract guarantee that the
data read back will either be correct (the checksum computed over the
data read from the disk matches the checksum stored on disk), or you
get an I/O error. Obviously, this greatly reduces the probability that
the data is invalid. (Particularly when taken in combination with the
disk firmware''s own ECC and checksumming.)

BTRFS partition won't mount

I recently had a power failure and can no longer mount my /home directory. The harddrive has two BTRFS partitions: sda7(/) and sda8(/home). The / partition loads up just fine, but /home does not. I''ve tried btrfsck as shown below and I''ve included dmesg pertaining to btrfs. This is on ArchLinux and the software versions are as follows:

Recovering "parent transid verify failed"
Hey,
I''d start by saying that I know Btrfs is a still experimental, and so
there''s no guarantee that one would be able to help me at all... But I
thought I''ll try anyway :-)
Few months ago I bought a new laptop and installed ArchLinux on it,
with Btrfs on the root filesystem... I know, it''s not the smartest
thing to do...
After a few month I had issues with my
