[Xen-users] memory problem, possible bug in testing
Hello, i have this problem: Hawaii0 xen # xm create Hawaii1 Using config file "Hawaii1". Error: I need 129 MiB, but dom0_min_mem is 128 and shrinking to 128 MiB would leave only 68 MiB free. But I really have enough memory. additional info: hawaii0 xen # xm info host : hawaii0 release : 2.6.16.13-xen version : #2 SMP Tue Jun 20 15:47:17 EDT 2006 machine : i686 nr_cpus : 2 nr_nodes : 1 sockets_per_node : 1 cores_per_socket : 1 threads_per_core : 2 cpu_mhz : 3010 hw_caps : 000325af:00000000:bfebfbff:20000000:00000000:00000180:0000649d total_memory : 1024 free_memory : 0 xen_major : 3 xen_minor : 0 xen_extra : .2-3 xen_caps : xen-3.0-x86_32 platform_params : virt_start=0xfc000000 xen_changeset : Sat Jun 17 12:48:07 2006 +0100 9749:ec2ac5a5f0a3 cc_compiler : gcc version 3.4.5 (Gentoo 3.4.5-r1, ssp-3.4.5-1.0, pie-8.7.9) cc_compile_by : root cc_compile_domain : (none) cc_compile_date : Mon Jun 19 15:50:56 Local time hawaii0 xen # cat Hawaii1 | grep -v ^# | grep -v ^$ kernel = "/boot/vmlinuz-2.6.16-xenU" memory = 128 name = "Hawaii1" vcpus = 2 vif = [ ''mac=00:16:3e:00:00:01, bridge=xenbr0, vifname=vif1.0'', ''mac=00:16:3e:01:00:01, bridge=xenbr1, vifname=vif1.1'', ''mac=00:16:3e:01:00:02, bridge=xenbr3, vifname=vif1.2''] disk = [ ''phy:hda5,hda1,w'' ] root = "/dev/hda1 ro" on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash = ''preserve'' hawaii0 xen # cat xend-config.sxp | grep -v ^# | grep -v ^$ (xend-relocation-server yes) (xend-relocation-hosts-allow ''^localhost$'') (network-script network-bridge) (vif-script vif-bridge) (dom0-min-mem 128) (dom0-cpus 0) hawaii0 xen # cat /boot/grub/menu.lst timeout 10 default 0 title Xen root (hd0,0) kernel /boot/xen.gz dom0_mem=200704 module /boot/vmlinux-syms-2.6.16.13-xen root=/dev/hda1 loopback.nloopbacks=32 title Xen / Linux.old root (hd0,0) kernel /boot/xen.gz dom0_mem=200704 module /boot/vmlinux-syms-2.6.16-xen root=/dev/hda1 loopback.nloopbacks=32 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] memory problem, possible bug in testing
I hit the same problem: xm reports zero free_memory as soon as xen0 boots. This seems to be due to xend using an old version of the pythong files. The bug happened when I only copied xen distribution files to /usr/lib/python/xen. If I copy from dist/install/usr/lib/python/xen to /usr/lib/python2.3/ and restarted xend, it sees free_memory. Must have to with XEN_PYTHON_NATIVE_INSTALL but I don''t do python and and just left that alone. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
