RE: [Xen-users] Error: Device ... could not beconnected.Hotplugscripts not working.
Tried appending the "raid=noautodetect" option to the boot line. Still hangs - it just skips the RAID initialization this time. Occasionally I can get one of my other servers (2.6.12, built from the Xen sources, instead of 2.6.13 kernel RPMS) to boot the guest into init, but it is very unstable and hangs often - usually while starting services.

I mean do you really have raid running in the guest? If not this may be causing a hang.

Well, I managed to clear the ''device could not be connected'' issues by upgrading udev. I''m not sure if SuSE does something funny with the RPM version, or if the 068 version has some issue, but upgrading to 077 seems to fix that message. But, I have a new problem. Now, when I go to boot the guests, the kernel boots and then the system just hangs. When I say hangs, I mean it is totally dead - console, SSH, everything. Attached is the output from the guest boot, which seems fairly normal. I''m also trying to watch all the log files to see if anything gets logged, but so far those look normal. Any suggestions on this one? Seems like maybe I need to disable something in the kernel somewhere, but I don''t know what. BTW, I did remove the dom0_mem directive from the startup...

In fact my problems was right when the guest was booting, after the kernel image was uncompressed and it tried to mount the device it failed. We could be talking about the same error. Try rebooting the host machine without the memory directive in grub and see if it works.

I''ll give it a try, but this is actually happening on two different systems. One has dom0_mem set to 131072 and one has dom0_mem set to 262144. It also isn''t limited to the NIC, it seems to be any device that the guest tries to access.

I had mine set to 131072. I never tried a different value but always when I had that one I got this error. When I removed that it went away and the guest Nic booted fine. Not sure if this is the same problem you have but it could be related and possibly this points you somewhere :) Regards, Jamie Moore -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Nick Couchman Sent: Friday, December 16, 2005 1:10 PM To: xen-users@lists.xensource.com Subject: [Xen-users] Error: Device ... could not be connected. Hotplugscripts not working. Well, it feels like I''ve been very needy lately, but I''m getting very frustrated trying to get Xen 3 to work. My latest problem is errors connecting devices. If I have a network card present in my domU configuration, I get the following error message on the command line: Error: Device 0 (vif) could not be connected. Hotplug scripts not working. If I set the configuration so that there are no NICs in the domU, I receive the following error message, instead: Error: Device 769 (vbd) could not be connected. Hotplug scripts not working. I have tried adding lines to the /etc/xen/scripts/block script (and other scripts) to debug it, including redirecting stderr output to another file, but I don''t get anything logged in the file. There is nothing to do with either udev or hotplug in my /var/log/messages file. I have udev 068, so the Xen installer installed the files necessary for using udev instead of hotplug. I''ve verified that the udev rule file is installed in the correct place, and udevd is running: xen-server00:~ # ps -ef | grep udev root 4384 1 0 13:58 ? 00:00:00 /sbin/udevd --daemon I''ve been through the list archives - both the user list and the developer list - looking for solutions, but none of the postings seem to apply to my situation, or at least trying the suggestions in those posting haven''t gotten me anywhere. I''m running a clean, lean install of SuSE10. I didn''t install the SuSE RPM''s for XEN, I downloaded the XEN source and built everything from source. Right now the only thing I''m trying to run is the simple ttylinux image provided on the XEN site for testing. I''ve attached the files xend.log, xend-debug.log, xend.trace (bzipped), and the domain configuration file (ttylinux). Can someone point out what in the world I''m missing that''s causing this headache? Also, I''ve verified that I have the necessary packages installed. bridge-utils is installed, and a quick glance at both "brctl show" and "ifconfig -a" show the the ethernet interfaces are being connected. The problems with the vbd seem to indicate that this isn''t limited to networking, though.
