[Xen-users] Xend crashes repeatedly starting DomU - please help...
Hi, this is a repost of a previous question - since then I have tried
rebuilding my Xen0 kernel numerous times and trying different
configurations, but I haven''t yet ever got a single DomU to boot so I
really don''t even know what is supposed to happen, let alone how to
start debugging it...
Can someone please speculate on how to debug this further? It''s a
gentoo hardened base build. I turned off the hardened compiler to build
the Xen0 kernel and the Xend demon, but all I get is a Sig11 every time
I try and start the new domain!! This is a brand new Dell server and it
has recompiled a lot of stuff (the whole installation several times!)
absolutely flawlessly so I don''t suspect any hardware problems
Are there any gentoo users here please who could at least note down some
basic steps that they took so I can at least try and get a ttylinux
domain running!!
Cheers

Hi, I have booted into a Dom0 kernel on a fairly stripped down machine
just running the basics needed. However, I haven''t yet managed to get
a
DomU booting. I constantly get the following error "Error: Received
invalid response from Xend, twice." on trying to start the domain
Where do I actually look to try and debug this further? I do have
SELinux compiled in on this kernel, but it''s in non-enforcing mode
nn1 xen # xm create -c ttylinux
Using config file "ttylinux".
Error: Received invalid response from Xend, twice.

The gentoo''s glibc''s one printed a message when killing the process iirc, the gentoo''s uClibc''s doesn''t seem to do so, as xend doesn''t get killed at this specific location any longer after having recompiled Python with vanilla-gcc (with no SSP, that is). (On gentoo uclibc-hardened, you can verify that SSP isn''t used by a specific binary any longer by doing "readelf -a /usr/bin/python | grep stack_smash_handler", it doens''t show anything if SSP is off.)

Hotplug scripts > | not working.I fixed this by replacing the udev I had installed with a working one (079 has never worked on ony of my other system here, which was 2.6.11- and is 2.6.12-based, but 070 works just fine. Xen-system kernel version is also 2.6.12).
