Iâve been fighting this for some time now, trying to get xen up and running so I can virtualize an old windows box and stuff it in my high-memory Linux system,
but for the life of me I cannot get this thing to obey dom0_mem.
Iâve edited /etc/default/grub and ran sudo update-grub several times with differing settings, but it refuses to pick up the settings it appears. Hereâs my
default grub file:
GRUB_DEFAULT="Xen 4.1-amd64"
GRUB_HIDDEN_TIMEOUT=10
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX="apparmor=0"
GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=4096M,max:4096M dom0_max_vcpus=2 com1=115200,8n1 console=com1,vga"
Am I missing something here? I can never get the memory I want out of these settingsâ itâs as if the kernel is completely ignoring them. Iâve tried with/without
the max segment, and all sorts of searches have turned up nothing. Are there XAPI settings too? I thought that /etc/xen/xend-config.sxp wasnât in play with XAPI, but I could modify that!
Uhâ sore forehead, anyone care to help me out here so I can issue the correct face palm to myselfâ I have to be missing something.
