Hello, We're testing Xen 3.0.1 changeset 8761 (Debian packages from http://packages.debianbase.de) with open-iscsi 1.0.485. Within dom0, everything runs fine, mounting LVM volumes from iSCSI target and using them (perf tests with bonnie++ for example) is OK. But when we try to create a domU with LVM-backed vbd on iSCSI, the machine reboots. The same domU with LVM-backed vbd on local scsi disks runs fine. Here's the console output : Unable to handle kernel paging request at virtual address 00100104 printing eip: c0147655 0ea36000 -> *pde = 00000000:dfeed001 1062d000 -> *pme = 00000000:00000000 Oops:
