This VM is on a public IP indeed, and SSH connectivity is enabled. As with any publicly accessible host this then becomes the target of ssh scans. I included the message just to show that between it and the reboot nothing had been logged. AFAICT there has not been a breach, and I have not seen any indications at all that there may be one.

There was no one logged in at the time of the reboot according to the last log. I did do some sysbench tests during the day, but that was way before it rebooted. The only thing that could be running during that time was daily periodic. $ sudo xm info host : soleus01.soleus.nu release: 2.6.32-5-xen-amd64 version: #1 SMP Mon Oct 3 07:53:54 UTC 2011 machine: x86_64 nr_cpus: 8 nr_nodes : 2 cores_per_socket : 4 threads_per_core : 1 cpu_mhz: 2200 hw_caps: 178bf3ff:efd3fbff::1310:00802001::37ff: virt_caps : hvm total_memory : 65534 free_memory: 6866 node_to_cpu: node0:0-3 node1:4-7 node_to_memory : node0:3128 node1:3737 node_to_dma32_mem : node0:3128 node1:0 max_node_id: 1 xen_major : 4 xen_minor : 0 xen_extra : .1 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit xen_pagesize : 4096 platform_params: virt_start=0x8000 xen_changeset : unavailable xen_commandline: placeholder dom0_mem=1852M cc_compiler: gcc version 4.4.5 (Debian 4.4.5-10) cc_compile_by : waldi cc_compile_domain : debian.org cc_compile_date: Wed Jan 12 14:04:06 UTC 2011 xend_config_format : 4 $ uname -a Linux soleus01.soleus.nu 2.6.32-5-xen-amd64 #1 SMP Mon Oct 3 07:53:54 UTC 2011 x86_64 GNU/Linux Jeroen. ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"

Hello Jeroen, So it looks like the system rebooted (but it was not a crash or a sporadic reboot? the kernel seems to be aware of the reboot request). It would be interesting if you could provide the output of the serial console when this happens, that might be helpful. Did you enable xenconsoled logging? Also, could you provide more info about your system, Xen version, what workload was the DomU running, Dom0 kernel version? ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
