Dear all, I have a reproducible issue with centos54 dom0 and debian lenny domU using pygrub. As far as I enter "shutdown -r now" in the running Debian Lenny DomU the whole system hangs. Keyboard is dead, network is dead and no more logging. Ending up in a hardware reset of the box. I was able to reproduce this 3 times. Restarting with xm reboot debian50 works without problems. Is there a possibility to debug this behavior? Unfortunately I neither had any logging in /var/log/* nor in /var/log/xen/* or on console. The debian lenny installation was done using debootsrap. No additional software has been installed in the debian domain. This is my cfg file for the Debian Lenny domain: bootloader = "/usr/bin/pygrub" memory = 1024 extra = "3" name = "debian50" vcpus = 1 vif = [ 'bridge=xenbr1' ] disk = [ 'phy:store/debian50_boot,xvda,w', 'phy:store/debian50_root,xvdb,w', 'phy:store/debian50_usr,xvdc,w', 'phy:store/debian50_var,xvdd,w', 'phy:store/debian50_tmp,xvde,w', 'phy:store/debian50_home,xvdf,w', 'phy:store/debian50_swap,xvdg,w', 'phy:store/compile,xvdh,w'] hostname = "debian50.zimmermann.com" on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' pci = [ '0000:09:04.0' ] Best Regards, Günter Zimmermann
