Hi, I'm trying to use DATABLOCK on our installation and have some issues. First, a little bit of context :
* Workers : - Xen 3.2, caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 - Debian Lenny, kernel 2.6.26-2, xen version, x86_64 * ONE : - ONE 2.0.1 - Centos 5.5, kernel 2.6.18-194 I use Xen in HVM mode, so my instances' template looks like : ---- CPU = 1 MEMORY = 256 OS = [ kernel = "/usr/lib/xen-default/boot/hvmloader" ] RAW =[type ="xen",data="builder='hvm'"] RAW =[type="xen",data="device_model='/usr/lib/xen-default/bin/qemu-dm'"] ---- Now the strange things : If I create a system image with DEV_PREFIX=sd, it own't boot. If I create it with DEV_PREFIX=xvd, it will boot correctly but will be seen as /dev/sda (and context will be /dev/sdb). With datablocks, it much more "funny", the only combination which seems to work is : - DEV_PREFIX=xvd for the system image - DEV_PREFIX=sd for the datablock image With this combination, resulting "onevm show" looks like : [snip] CPU=1 DISK=[ CLONE=YES, DISK_ID=0, IMAGE=BonFIRE Debian Squeeze v2, IMAGE_ID=165, READONLY=NO, SAVE=NO, SOURCE=/srv/cloud/one/var/images/58cad9fd025f8135a4ef176a0f7721826a0aea8e, TARGET=xvda, TYPE=DISK ] DISK=[ CLONE=YES, DISK_ID=1, IMAGE=bd18, IMAGE_ID=283, READONLY=NO, SAVE=NO, SOURCE=/srv/cloud/one/var/images/ec02c9e15e297d51c94ef9640909bee7345eb529, TARGET=sde, TYPE=DISK ] [snip] So the system disk has xvda as target, but will finally appear as /dev/sda. Context will appear as /dev/sdb, and the datablock which has target=sdE will appear as /dev/sdc ... any other combination does not work for me (if TARGET=sda for system disk, instance does not boot, if TARGET=xvdX for datablock, the instance boots but the corresponding device never appears).
