 It works for me but I do not recall if I was originally able to
 reproduce the issue with the whole device disk configuration I
 typically use and I don't have an easy way to construct a partitions
 only configuration at the moment. IIRC Ferenc (the original reporter)
 was using the partition based scheme so perhaps he can confirm if it
 works for him now.

Ferenc, any news on that? Would be great if you could
give initramfs-tools =0.95.1 a try.

 Ferenc seems to be using the xvda1=img1,xvda2=img2 scheme of Xen disks
 (this is what xentools gets you) rather than the whole disk with
 partition scheme.
 
 In the xvda1/xvda2 scheme /sys/block contains:
 # ls /sys/block/
 ram0  ram1  ram10  ram11  ram12  ram13 ram14  ram15  ram2  ram3
 ram4 ram5  ram6  ram7  ram8 ram9  xvda1  xvda2
 
 In the whole disk scheme it contains xvda as you would expect:
 # ls /sys/block/
 loop0  loop1  loop2  loop3  loop4  loop5  loop6  loop7 ram0
 ram1  ram10  ram11  ram12  ram13 ram14  ram15  ram2  ram3  ram4
 ram5  ram6  ram7  ram8 ram9  xvda

thanks for the analysis and the explanation.
 
 I've attached a patch which takes care of this difference. However the
 modules still aren't loaded.

hmm what?
which modules are not loaded?
 
 Note that the -xen type images seem to have the block driver builtin
 (and therefore work fine) while the -686-bigmem ones have it modular
 (xen-blkfront.ko) and break with MODULES=dep.

argh,
the syswalking doesn't add that one?
could you post output with MODULES=dep for the modular case of
sh -x mkinitramfs -o /tmp/foo
 
 I've attached ls -lRt of my /sys running -686-bigmem
 and /sys/devices/vbd-51712/modalias contains xen:vbd which is present
 as an alias on the xen-blkfront.ko module. Any other info required
 please ask.
 

thanks for the patch bellow i'll apply it asap,
as it is an improvement anyway

well also according to the /sys tree you posted [1] this seems

 update-initramfs: Generating /boot/initrd.img-2.6.26-1-xen-686
 mkinitramfs: missing xvda root /dev/xvda1 /sys entry
 
 So here you are.  This virtual machine has a single virtual partition
 (/dev/xvda1) imported, no /dev/xvda.

hmm could you please post the output of
ls /sys/block

so that i can add the relevant rule for xen block devices.

Bug#501359: initramfs-tools: MODULES=dep does not like Xen virtual block devices

2008-10-06 Thread Ferenc Wagner 
Package: initramfs-tools
Version: 0.92j
Severity: normal

Hi,

when trying to build a small initramfs via MODULES=dep:

$ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-2.6.26-1-xen-686
mkinitramfs: missing xvda root /dev/xvda1 /sys entry
mkinitramfs: workaround is MODULES=most
mkinitramfs: Error please report the bug
update-initramfs: failed for /boot/initrd.img-2.6.26-1-xen-686

So here you are.  This virtual machine has a single virtual partition
(/dev/xvda1) imported, no /dev/xvda.

Thanks,
Feri.
