[Xen-users] Error: The privileged domain did not balloon! after reboot of Dom0, it just works
Hi, I try to setup a linux ha based cluster, managing virtual Xen domU resources. When the cluster is up for e.g. a day or two, and then I want to move the Xen domU''s from one host to another, I get the following errors in the logfile: lrmd[9971]: 2007/11/12_11:20:53 info: RA output: (NFS_SW:start:stderr) Error: The privileged domain did not balloon! This also happens when I then try to start the domU instance via xm create When I then reboot the dom0, then xm create works fine again without problems. So this behaviour is useless, when it comes to a fail-over in the cluster after a week or so. When both cluster nodes started up, the migration of the resources from one host to another work well. Is there a way to prevent this failure, sth. I can do? kind regards Sebastian xm info host : ppsdb101 release : 2.6.16.46-0.12-xen version : #3 SMP Wed Oct 24 22:07:07 CEST 2007 machine : x86_64 nr_cpus : 4 nr_nodes : 1 sockets_per_node : 2 cores_per_socket : 2 threads_per_core : 1 cpu_mhz : 2205 hw_caps : 178bfbff:e3d3fbff:00000000:00000010:00000001:00000000:00000002 total_memory : 3927 free_memory : 34 max_free_memory : 34 max_para_memory : 30 max_hvm_memory : 21 xen_major : 3 xen_minor : 0 xen_extra : .4_13138-0.40 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : 13138 cc_compiler : gcc version 4.1.2 20070115 (prerelease) (SUSE Linux) cc_compile_by : abuild cc_compile_domain : suse.de cc_compile_date : Fri May 18 13:26:05 UTC 2007 xend_config_format : 3 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I can do?Try limiting dom0s memory so it does not have to balloon. This is done in your boot manager: /boot/grub/menu.lst ... title XEN3.1.0 root (hd0,0) kernel /boot/xen-3.1.0.gz dom0_mem=256M dom0_vcpus_pin ^^^^^^^^^^^^^ module /boot/vmlinuz-2.6.18-xen root=/dev/sda1 module /boot/initrd-2.6.18-xen ...
