Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops)
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.
Boris.

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
module (hd0,13)/vmlinuz-2.6.31
module (hd0,13)/initrd-2.6.31.img
}
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. -- Keir On 11/09/2009 10:00, "Boris Derzhavets" < bderzhavets@xxxxxxxxx> wrote: > > > > > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxxhttp://lists.xensource.com/xen-devel
