I have managed to get this working with the aid of some hacks to the UDEV configuration files so that I can get a deivce entry like /dev/magical-iscsi-targetname.my.fun.domain.com.Hi, I am having problems getting iSCSI working with xen. I can access iSCSI drives fine from Xen0 (e.g. untar a 500MB archive and I don't see problems reported through dmesg or /proc/kmsg). However, if I try to project them into an instance of XenU as a scsi device to boot the unprivileged domain I get an oops in Xen0 - often resulting in the whole machine crashing. This occurs in the very early stages of boot of xenU. I am using linux-iscsi-4.0.2 for iscsi_sfnet.ko scsi_transport_iscsi.ko is being built in linux-2.6.12-xen0 I downloaded xen-unstable-src.tgz October 25th. I notice that there appear to be some significant differences betweenscsi_transport_iscsi.c in linux-iscsi-4.0.2 and the version in linux-2.6.12 kernel.Example oops below. I have also attached the domain config file. I am not sure what to do next to get this working. Any suggestions would be appreciated. If you have iSCSI working, if you could drop me a note indicating what code and modules you are using I would be very grateful. Cheers, Nigel. It is then easy to map these things into the approprate DomU configs.I would be concerned about using iSCSI in the DomU's because of the extra network overhead in propigating the data across the bridge. -- Alvin Starr || voice: (416)585-9971 Interlink Connectivity || fax: (416)585-9974 alvin@xxxxxxxxxx || _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
