Questions from a newbie (how to reboot/ windows vista crashing machine)
Hi all, I started playing with xen on fedora 19 and really enjoying it. I have some questions. 1. When I reboot dom0 by simply typing reboot, it gets stuck. Is there another way to reboot dom0? 2. When I try running windows vista under a domU HVM, it works fine until I reboot the domU or force shutdown of the domU which causes the entire machine (hypervisor/dom0) to crash and reboot. I tried using the cfg from the wiki and also tried using virtual manager. Where do I look to try to see what is going on? is windows on xen? Haiku and various Linux runs fine in the domU HVM. http://www.virtuatopia.com/index.php/Installing_and_Running_Windows_XP_or_Vista_as_a_Xen_HVM_domainU_Guest [root@]# rpm -qa |grep xen xen-licenses-4.2.2-10.fc19.i686 xen-4.2.2-10.fc19.i686 xen-libs-4.2.2-10.fc19.i686 libvirt-daemon-xen-1.0.5.2-1.fc19.i686 libvirt-daemon-driver-xen-1.0.5.2-1.fc19.i686 xen-hypervisor-4.2.2-10.fc19.i686 xen-runtime-4.2.2-10.fc19.i686 [root@]# xl info host : release : 3.9.9-301.fc19.i686.PAE version : #1 SMP Thu Jul 4 15:25:09 UTC 2013 machine : i686 nr_cpus : 4 max_cpu_id : 3 nr_nodes : 1 cores_per_socket : 4 threads_per_core : 1 cpu_mhz : 2666 hw_caps : bfebfbff:20100000:00000000:00000940:0408e3bd:00000000:00000001:00000000 virt_caps : hvm total_memory : 8190 free_memory : 128 sharing_freed_memory : 0 sharing_used_memory : 0 free_cpus : 0 xen_major : 4 xen_minor : 2 xen_extra : .2 xen_caps : xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=0xf5800000 xen_changeset : unavailable xen_commandline : placeholder cc_compiler : gcc (GCC) 4.8.1 20130603 (Red Hat 4.8.1-1) cc_compile_by : mockbuild cc_compile_domain : phx2.fedoraproject.org cc_compile_date : Wed Jun 26 19:18:01 UTC 2013 xend_config_format : 4 _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

If you want more than my WAG answer, please provide more details (system logs, error messages, etc.). That being said, my WAG is that you''re not shutting down your domUs before you shutdown your dom0. To prevent headaches, ensure there are no running domUs before you attempt a shutdown/reboot of dom0.> 2.

The man pages are your friend here. If the crash is hard enough, it may not get written to disk. In that case, you''ll want to get a serial console set up and log the crash messages to another machine. --Sean
