Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server
dmesg log for 2.6.31-rc6 is attached.
Xen-bus activation entries are present in the log.

One more notice.
Jeremy''s 2.6.31-rc6 kernel just several times caused xend failure to
start.
Actually, 2.6.31-rc6 hadn''t problems with supporting Dom0 on top of
Ubuntu 9.10 , i.e. xend started almost every time.
2.6.29.6 & 2.6.30.2 xenified kernels also don''t have any problems
with
xend startup after loading Dom0.
It seems to me as issue dependent on kernel supporting Dom0, first time raised
up for 2.6.31-rc9.
On the other hand 2.6.31 works fine under Xen 3.4.1 on top of Ubuntu 9.04
Server.
Xen port to Ubuntu is done every time via tuning Config.mk to place xen folder
under /usr/local/lib/phyton2.6/dist-packages.

Suggestion below has been used to load Dom0 via grub entry:
menuentry "Xen 3.4 / Ubuntu 9.10 kernel 2.6.31" {
insmod ext2
set root=(hd0,13)
multiboot (hd0,13)/xen-3.4.gz

Dom0
was loaded OK.
However, /etc/init.d/xend start generates xend.log :-

There is no supported way, as we expect to have a sane bootloader that can
parse boot args. If youw ant to hack it in, edit the line ''cmdline
cmdline_cook(...'' in arch/x86/setup.c to read ''cmdline =
"my args go here";''
instead.

Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server
In meantime when loading the most recent 2.6.31 pvops kernel under Xen Unstable
on top of Ubuntu
9.10 Server (alpha 4, apt-get update, apt-get upgrade -> grub 1.97~beta2) i
get a message:
/proc/xen is already mounted on xenfs ( xenfs is busy)
what causes daemon xend failure to start. Xen-bus appears not to be activated
during Dom0 loading.
As usual i added to /etc/fstab before loading Xen Host :-
none /proc/xen xenfs defaults 0 0
as did it on 9.04. Might it be a mistake on 9.10 (or alpha bug) ?
Boris.

Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server
I''ve been following along on this thread as I''m also using the pv-ops kernel on 9.04. Perhaps 9.10 already mounts /proc/xen and as such doesn''t require the fstab entry. If this is the case that would explain the "already mounted" error message. -Bruce On Sun, Sep 13, 2009 at 10:38 AM, Boris Derzhavets <bderzhavets@yahoo.com>wrote:> > In meantime when loading the most recent 2.6.31 pvops kernel under Xen > Unstable on top of Ubuntu 9.10 Server (alpha 4, apt-get update, apt-get > upgrade -> grub 1.97~beta2) i get a message: > > /proc/xen is already mounted on xenfs ( xenfs is busy) > > what causes daemon xend failure to start.

Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server
OK. I removed "xenfs" entry from /etc/fstab and /etc/mtab and attempted to load Xen Unstable Host (2.6.31). No errors been sent to console ( vs usual situation). "xenfs" record appears automatically to be added to /etc/mtab , however xen-bus has not been activated during Dom0 load, hence xend appears unable to start when Dom0 gets loaded.

Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server (seems to be Xen bug)
Another attempt. Cleaned up /etc/mtab. Restarted Xen Host (without xend)
TO MAKE SURE "xenfs" record is supposed to be added via xend startup
per CS you mentioned.
Loged into Dom0 and checked that file /etc/mtab is clean. Then attempted:-
# /etc/init.d/xend start
Failure, however "xenfs" entry has been added to /etc/mtab.

OK. I removed "xenfs" entry from /etc/fstab and /etc/mtab and
attempted to
load Xen Unstable Host (2.6.31). No errors been sent to console ( vs usual
situation). "xenfs" record appears automatically to be added to
/etc/mtab , however xen-bus has not been activated during Dom0 load,
hence xend appears unable to start when Dom0 gets loaded.

Latest xen-unstable contains code to automatically mount xenfs from xend start.

Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server (seems to be Xen bug)
I believe successful xend startup should generate lines like:-

It does not happen on Ubuntu 9.10 during booting up Xen Unstable with kernel

Another attempt. Cleaned up /etc/mtab. Restarted Xen Host (without xend)
TO MAKE SURE "xenfs" record is supposed to be added via xend startup
per CS you mentioned.
Loged into Dom0 and checked that file /etc/mtab is clean. Then attempted:-
# /etc/init.d/xend start
Failure, however "xenfs" entry has been added to /etc/mtab.

OK. I removed "xenfs" entry from /etc/fstab and /etc/mtab and
attempted to
load Xen Unstable Host (2.6.31). No errors been sent to console ( vs usual
situation). "xenfs" record appears automatically to be added to
/etc/mtab , however xen-bus has not been activated during Dom0 load,
hence xend appears unable to start when Dom0 gets loaded.

Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server (seems to be Xen bug)
Finally, i was able to setup Xen 3.5 Dom0 ( with 2.6.31 kernel) on top of Ubuntu
9.10
Server (alpha 4 , apt-get upgraded) , keeping /etc/fstab free from
"xenfs" entry.
However, creating new F11 PV DomUs randomly causes dropping Xen Console into
stack trace and loosing vnc connection to Xen 3.5 Dom0.
Boris.
P.S. xen-3.5.gz compiled via hacking ./xen/arch/x86/setup.c and setting
cmdline="dom0_mem=1024M";

It does not happen on Ubuntu 9.10 during booting up Xen Unstable with kernel

Another attempt. Cleaned up /etc/mtab. Restarted Xen Host (without xend)
TO MAKE SURE "xenfs" record is supposed to be added via xend startup
per CS you mentioned.
Loged into Dom0 and checked that file /etc/mtab is clean. Then attempted:-
# /etc/init.d/xend start
Failure, however "xenfs" entry has been added to
/etc/mtab.

OK. I removed "xenfs" entry from /etc/fstab and /etc/mtab and
attempted to
load Xen Unstable Host (2.6.31). No errors been sent to console ( vs usual
situation). "xenfs" record appears automatically to be added to
/etc/mtab , however xen-bus has not been activated during Dom0 load,
hence xend appears unable to start when Dom0 gets loaded.
Boris.

Latest xen-unstable contains code to automatically mount xenfs from xend start.
