[Xen-devel] RAMDISK-Boot: Not enough RAM for domain 0 allocation.
Hello,
I''m trying to boot xen-3.3 from network with linux on a ramdisk, but
this fails with the output below:
this are my boot-settings:
default xen-linux
prompt 1
timeout 10
label xen-linux
kernel mboot.c32

After some researching, I''ve found this
thread(http://lists.xensource.com/archives/html/xen-devel/2008-08/msg00518.html),
but the solution doesn''t work for me.
Thanks in advance

Re: [Xen-devel] RAMDISK-Boot: Not enough RAM for domain 0 allocation.
Xen wants to allocate smallest power-of-two sized memory block which will fit both kernel and initrd. This will be 2GB on your system, and there is no such 2GB aligned block. Either this restriction of the domain builder needs to be lifted (a bit of a pain and not really on anyone''s todo list), or you could just reduce your initrd size by 100MB and cross your fingers -- it''s likely that Xen will be able to find an aligned 1GB memory block. -- Keir On 7/10/08 09:08, "viets@work.de" <viets@work.de> wrote:> Hello, > > the image has a size of 1048576 kilobytes uncompressed. > > greetings > Torben > > Keir Fraser wrote: >> On 7/10/08 08:37, "viets@work.de" <viets@work.de> wrote: >> >>> Hello, >>> I''m trying to boot xen-3.3 from network with linux on a ramdisk, but >>> this fails with the output below: >>> >>> this are my boot-settings: >>> >>> default xen-linux >>> prompt 1 >>> timeout 10 >>> >>> label xen-linux >>> kernel mboot.c32 >>> append xen-3.3.0.gz noreboot dom0_mem=2097152 console=com2 >>> com2=115200,8n1 --- vmlinuz-2.6.18.8-xen0 root=/dev/ram >>> ramdisk_size=1048576 console=tty0 console=ttyS1,115200 --- jobserver.img.gz >>> >> >> How big is the ramdisk image, uncompressed? >> >> -- Keir >> >> >> >> _______________________________________________ >> Xen-devel mailing list >> Xen-devel@lists.xensource.com >> http://lists.xensource.com/xen-devel >> >_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
