VMware and multiple vmdk files
by Thierry Thelliez 03 Jun '10

03 Jun '10

With VMWare (server), you can pre-allocate your image in several vmdk files. But I have not bee able to mount that in guestfs. On file (e.g. guest.vmdk) is a text file pointing to all the other files (e.g. guest-f001.vmdk, guest-f002.vmdk,...). I tried the following scenarios without success: 1- just adding the base vmdk: add_drive guest.vmdk 2- adding all the files: add_drive guest-f001.vmdk add_drive guest-f002.vmdk ... It works if I merge all the files with vmware-vdiskmanager (something like: vmware-vdiskmanager -r guest.vmdk -t 0 guest-new.vmdk) Can I use guestfs without merging all the files in one image? Thanks, Thierry

uninstall vmware tools on v2v to kvm?
by Amos Benari 02 Jun '10

02 Jun '10

Hi, I have tested the windows v2v from esx to kvm with vmware-tools installed on the guest. There is an issue, a message on first login after boot that tell the user that one or more services failed to start. In the system event log there are 3 errors. Two of them are tool services and one is the parallel port driver service. Disabling the services (setting start mode 4 in the registry) solved the issue. Running the tools uninstaller failed with a message saying it will not uninstall if it's not running on VMware hypervisor. Looking at the guest registry I have found 8 VMware services, I think that uninstalling the tools entirely might be too intrusive, If someone is really bothered by some extra files on the file system they can uninstall on the original esx. I think we should, disable all the tools services on the v2v scripts using the windows converter and hivex. If this sounds like the correct solution I'll try to write it. Amos

[PATCH] parted: Check partition number >= 1 in several calls.
by Richard W.M. Jones 02 Jun '10

02 Jun '10

This patch depends on the previous one, but is logically independent from it. It simply adds checks that the partition number >= 1 for all those part-* calls that take a partition number.

[PATCH] daemon: Parse output of old parted which didn't support -m option (RHBZ#598309).
by Richard W.M. Jones 02 Jun '10

02 Jun '10

RHEL 5's old parted didn't have the -m option. A number of commands relied on this option and thus would break on RHEL 5: https://bugzilla.redhat.com/show_bug.cgi?id=598309 This rather large patch adds a second parsing path which allows us to parse the old text-based output (it preserves the code for parsing the output of the -m option too, since if supported, that is more accurate). Typical output from the old format looks like this: --- Model: Unknown (unknown) Disk /dev/vda: 524287999B Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 512B 524287999B 524287488B primary boot --- Tested on RHEL 5.5.

[PATCH] daemon: count_strings function returns size_t
by Richard W.M. Jones 02 Jun '10

02 Jun '10

The return value from count_strings can only ever be >= 0, so it should be a size_t not an int. This is in preparation for fixing 598309, but I'm still testing that (rather large) patch.
