...ff I will be mirroring here: http://mirror.orionvm.com.au/pub/ Initially there is Debian 6, CentOS 6.2 and Ubuntu 12.04 available (the final beta, will be updated to final shortly). Included is an OS image, a config file, a README and the associated licences etc. The images are bz2 compressed blockdevice images suitable for use on LVM or a file backed tapdisk if you have the appropriate backend. (alternatively you can use the loop device but this is discouraged) All images have serial console enabled, PV network and block devices, fixed udev rules etc. I will add more info about them, an FAQ about...

Figure I'd share the latest revision to p2v I had regarding $subject. The patch now applies against HEAD and compiles fine. I was able to update the package on the client and run virt-p2v, though have yet to do a full end-to-end verification Most likely a little more work is needed to tidy up some edge cases and fully flush things out, but the majority of the work should be in place. On the

...vicefile and that the size is 0, and so the sender does send over zero bytes Now here is the problem : How do I get the size of partition in this datastructure ? Or more generique, how would I handle this for /dev/fd0, since you can insert 1.44MB disks or 720kB disks ? Anybody else tried to read blockdevices over rsync already ? After all, sending the data of a block device doesn't seem to be as trivial as the archived mail sugested :-) David -------------- next part -------------- HTML attachment scrubbed and removed

...ynchronize block devices: BDsync. Bdsync can be used to synchronize block devices over a network. It generates a "binary diff" in an efficient way by comparing MD5 checksums of 32k blocks of block devices. This binary diff can be applied to "destination" after which the local blockdevices are synchronized. bdsync was built to do the only thing rsync isn't able to do: synchronize block devices. But I would actually like rsync or another tool te replace bdsync ASAP. Interrested people can download the sources from: http://bdsync.rolf-fokkens.nl/ Rolf -------------- next part...

...9;s at all possible to live resize a disk image. After trying and failing it seems that the reason a disk image cannot be resized - is that domU is only able to detect changes in partitions (eg. partprobe), not in block devices as the xvd driver lacks a rescan feature. My domU sees disk images as blockdevices - that is without a partition table, and I cannot find a way to boot a domU from a partition within a disk image? But if I could get XEN to boot a domU from a partition on a disk image, I assume the domU via partprobe would see if I resized the partition and could then resize the filesystem? Or...

Hi, dom0: Debian Lenny 2.6.26-2-xen-amd64, domU: same. Xen 3.2-1 After resizing a LV on dom0, Xen is not reporting the new extended size to the PV domU even though dom0 is well aware of the new size. I''ve rebooted domU (not dom0 yet as that''s running a lot of other domU''s). The LV I tried to resize is encrypted. Resizing unencrypted volumes works as expected. dom0:~#

hello ! i try to use a network technology on one single host, which wasn`t designed for that. to give a short overview of what i`m talking about: AoE is just like a "networked blockdevice" (just like nbd/enbd) - but without tcp/ip. AoE kernel driver is the "client end" (see this like an iSCSI initiator) - and an etherblade storage appliance is the "server end" (see this like an iSCSI target) there is a software equivalent to etherblade storage which is call...

...ith a vanilla 3.2 (3.2.0/3.2.6) kernel as Dom0 and stock RHEL/CentOS 6.x guests as HVM/pv-ops DomUs. Our DomU''s have their disk-devices on iscsi-storage backends (EMC, netapp, Linux IET), we attach the disks to Dom0 via open-iscsi initiator and pass them as ''phy''-type blockdevices, using blkfront/back. As this is the time for a major overhaul anyway, I looked at ''pvscsi'', which is very attractive to me for a bunch of (administrative) reasons. I have created a working pvscsi-setup with the following steps: 1. Use CentOS 6.2 as base system 2. Add Xen hype...

Hi, By running some scripts on our target system for a while, I lost all means of access to the system. It seems that the kernel is crashed with the following error message: Assertion failure in do_get_write_access() at transaction.c:731: "(((jh2bh(jh))->b_state & (1UL << BH_Uptodate)) != 0)" Oops: Exception in kernel mode, sig: 4 We are currently running Linux version

...akes the wrong approach, IMO. >From how I understand btrfs, it has the concept of subvolumes. Each one is an entry point for a separate filesystem. In addition to that it has a default subvol which is used if no specific subvolume is specified. This turns the whole btrfs partition (or assembled blockdevice) into a container of individual filesystems. But guestfs, as far as I understand it, just mounts the btrfs filesystem with the default subvolume and ends up somewhere. Then it tries to make sense of the other subvolumes based on info from a /etc/fstab, which may or may not exist. This looks like...

...r-GUI - snapper rollback - yum-plugin - every option. - grub2-btrfs The only thing I still want to care is the grub2-btrfs plugin, so it fits to CentOS 7. Then the personal project is done. At this time I will reinstall CentOS on my laptop on btrfs and use backup by send & receive on a blockdevice ZFS at my home server or other storage with btrfs. I will see. Hopefully turn work into fun :-). Sincerely Andy PS: It's up to you to get a taste on.
