[Xen-devel] Attempt to load 2.6.31 under Xen 3.5 on top of Ubuntu 9.04 Server (dom0_mem has not been specified)

System loads to boot.
dom0_mem=1024M resolves problem.

[Xen-devel] Re: Attempt to load 2.6.31 under Xen 3.5 on top of Ubuntu 9.04 Server (dom0_mem has not been specified)

Typo.
System fails to boot without dom0_mem=1024M (2048M) at xen.gz line.

Re: [Xen-devel] How to build xen.gz with static built-in command line dom0_mem=1024M ?

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] How to build xen.gz with static built-in command line dom0_mem=1024M ?

  Works for loading Dom0 ( JF''s 2.6.31) under both Xen 3.4.1 and Xen
3.5
via both Grub legacy & Grub2.

Still have one issue , regarding Ubuntu Servers not Xen.
xend starts fine on 9.04 ( Grub Legacy)
xend fails to start on 9.10 alpha 4 ( Grub2)

Thanks.
Boris.

Grub/Grub2 doesn''t have anything to do with xend.

The issue is somewhere else.

[Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server

Suggestion below has been used to load Dom0 via grub entry:

menuentry "Xen 3.4 / Ubuntu 9.10 kernel 2.6.31" {

Re: [Xen-devel] Failure to start xend in Xen 3.4.1 Dom0 ( 2.6.31 pvops) on top Ubuntu 9.10 Server

 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.
