https://bugzilla.novell.com/show_bug.cgi?id=347416 Summary: OpenSuse 10.3, Xen 3.1.0, unable to install domU over http, entire physical server hangs and crashes Product: openSUSE 10.3 Version: Final Platform: i686 OS/Version: openSUSE 10.3 Status: NEW Keywords: dogfood Severity: Blocker Priority: P5 - None Component: Xen AssignedTo: cgriffin@novell.com ReportedBy: gb2@c5i.net QAContact: qa@suse.de Found By: Customer When running OpenSuSE 10.3 (kernel 2.6.22.13-xenpae) on a Dell PowerEdge 2950, and Xen 3.1.0, attempts to install an copy of OpenSuSE 10.3 as a domU instance while reading the source via http:// to the local dom0 host results in the entire physical server freezing at random points during the installation of packages. * This has been duplicated on four seperate Dell 2950 servers with different configurations and manufacture dates. * This occurs in both graphical (i.e. KDE/VNC) mode as well as text (i.e. xenconsole) mode, and in both runlevels 3 and 5. * Some had suspected that this might be related to bug 344877, which complains about dom0 hanging under high traffic load, and indeed it did seem to fit the profile; however, a modified kernel set to 100Hz did *not* resolve this problem. Moreover, I cannot duplicate that bug. My installations crash within 5-10 minutes of starting. But I ran "ping -f -q my.local.ip.address" for an hour with no problems: core1:/home/glen # ping -f -q my.local.ip.address PING nnn.nnn.nnn.nnn (nnn.nnn.nnn.nnn) 56(84) bytes of data. --- nnn.nnn.nnn.nnn ping statistics --- 196356167 packets transmitted, 196356167 received, 0% packet loss, time 3573391ms rtt min/avg/max/mdev = 0.010/0.010/30.037/0.003 ms, pipe 2, ipg/ewma 0.018/0.011 ms The ping flood ran successfully for hours under both the loopback address and the public-facing IPV4 address. * I am unable to install from the CD due to bugs in the vm-install python script. * My web server is just the stock apache2 server with the document root re-set to /opensuse, a directory off root which contains a copy of the installation CD. * All the troubleshooting steps in /usr/share/doc/packages/xen/README.SuSE have been followed, including booting with different kernel parameters such as pnpacpi=off, lapic, acpi=off, apm=off, noirqbalance, etc. * I also tried to grab output using sync_console, xm dmesg, etc. No log or serial output is generated, no evidence of a panic exists. The hardware... just.... stops. * Obviously, this bug prevents the use of Xen at all on any of my servers. (Plus, any bug which allows a domU instance to reach out and crash the dom0 box would certainly be a show-stopper in any event.) Please let me know how I can assist with the resolution of this bug, as we cannot move to 10.3 or use virtualization until this is corrected.
