[Xen-devel] Out of memory when start DomU.

[eXeC001er <execooler@xxxxxxxxx>]

Hi.

my grub cfg:

menuentry "Xen 4.1 / Debian Squeeze kernel 2.6.32-4 pvops" {

        insmod ext2

        recordfail=1

        if [ -n ${have_grubenv} ]; then save_env recordfail; fi

        set quiet=1

        search --no-floppy --fs-uuid --set 6a21fff8-973c-4367-a689-e0d183b16024

        set root='(hd0,1)'

        multiboot (hd0,1)/boot/xen-4.1.gz loglvl=all guest_loglvl=all

#        multiboot (hd0,1)/boot/xen-3.4-amd64.gz loglvl=all guest_loglvl=all

        module (hd0,1)/boot/vmlinuz-2.6.32-4-xen-amd64 ro root=/dev/sda1 loglevel=10

        module (hd0,1)/boot/initrd.img-2.6.32-4-xen-amd64

}

I tried to start my DomU (Opensolaris b134):

xm create my_domu.py -c

Using config file "./my_domu.py".

Error: (4, 'Out of memory', "xc_dom_boot_mem_init: can't allocate low memory for domain\n")

same configuration works fine on xen-3.4 from Debian Squeeze.

Thanks.
