...ot any domUs via pygrub. As a test I've just pulled pygrub out of xen-tools-4.5 from experimental but I'm still getting the same error in the bootloader.log: ---- Traceback (most recent call last): File "/usr/lib/xen-4.4/bin/pygrub", line 809, in <module> part_offs = get_partition_offsets(file) File "/usr/lib/xen-4.4/bin/pygrub", line 106, in get_partition_offsets image_type = identify_disk_image(file) File "/usr/lib/xen-4.4/bin/pygrub", line 48, in identify_disk_image fd = os.open(file, os.O_RDONLY) OSError: [Errno 2] No such file or directory: '...

Hi, we are still experiencing this error on stable jessie with xen 4.4.1 and it does not appear to be fixed in that version at all. The actual error is: -- snip -- Traceback (most recent call last): File "/usr/lib/xen-4.4/bin/pygrub", line 809, in <module> part_offs = get_partition_offsets(file) File "/usr/lib/xen-4.4/bin/pygrub", line 106, in get_partition_offsets image_type = identify_disk_image(file) File "/usr/lib/xen-4.4/bin/pygrub", line 48, in identify_disk_image fd = os.open(file, os.O_RDONLY) OSError: [Errno 2] No such file or directory:...

...think this is because of the function "is_disk_image" on line 45 of /usr/lib/xen-4.1/bin/pygrub: it should return false on LVM LV's because they are not disk images but virtual devices, but it returns true because of certain bytes in the first block of 512 bytes being set. This causes get_partition_offsets to seek fruitlessly for a partition instead of simply returning [0], causing the bootloader not to find the right partition. Detailed steps to reproduce: We have a domU called blup.kassala.de, it is running Jessie, its root disk is a LVM LV at /dev/vpsdisks/blup.kassala.de-disk. The first 512 byte...

I'm afraid I don't follow your logic here. is_disk_image is trying to determine whether or not the device (be it a virtual device or otherwise) contains a parti...

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous
