Pkg xen devel - Jan 2016 - Bug#812327: xen: initrd booting with xen don't find any harddisks

Package: xen-system-amd64
Version: 4.6.0-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

I installed fresh from ALPHA5, no UEFI, with two disks. Each disk
got a partition for /boot and one for /, joined each by RAID 1.

Then I just installed "xen-system-amd64", nothing more. After
rebooting, selecting on grub to boot XEN, it hangs on

  mdadm: no devices listed in conf file were found

. I reproduced this on a different machine, and there is the same case.

In initrd you can see that it just do not have any /dev/sd* or
/dev/hd*. So it is clear why it cannot find the arrays.

Why does the kernel not find any disks booting via XEN? If you select
in grub the entry without xen, it just finds its discs and boots fine...

Please can you post full boot logs of the successful (without Xen) and
unsuccessful (with Xen) cases using the exact same kernel + initrd binaries
(i.e. the only difference being the presence of Xen under the kernel)

Thanks,
Ian.

(adding the bug back, please keep it ccd)

At least the linux dmesg in both cases, yes.

In the Xen case if you can get the Xen dmesg one too (which you may not
from a initrd) that would be useful as well.

In the Xen case you might find?http://wiki.xenproject.org/wiki/XenSerialCon
sole?useful (if your hardware has a serial port, which is less common these
days). Failing that a digital photo of all the bits with (XEN) at the front
(a big block near the start of boot and possibly odd bits in the middle of
the dom0 logs later) would be better than nothing.

Ian.
