I've been asked to point out there are really two problems: 1. If the emulated devices (i.e. the "real" sda) is not unplugged, there is a device name clash. The emulated devices cannot be unplugged on xen 3.3 (because it doesn't support it), but unless you pass unplug=unnecessary, it won't actually allow the PV drivers, so you lose PV support. On 3.4 and onwards you might pass unplug=unnecessary anyway to get consistent device mapping with xen 2.6.18 supplied kernel, in which case you will get the device name clash. 2. Even if the unplugging works, you then get inconsistent device mapping, because both mainline, 2.6.18 and everything else expect to see virtual devices under /dev/xvda, not /dev/sda, so although you won't get the clash (i.e. the failure to register the device), the device will have an unexpected name which can and will break stuff. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/684875 Title: Patch to Natty 2.6.37-virtual breaks non-EC2 users -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
