Whenjobs automating libguestfs development version test & build

by Richard W.M. Jones

Just a note that 'whenjobs'[1] is now automating libguestfs test and build, along the development branch. Simply tagging a new release in git will trigger a cycle of packaging, test, build, updating the website, and performing a new build in Fedora Rawhide. At the moment I'm only doing the tests on Fedora, but I will extend it later so it tests both individual commits and released tarballs on Debian, Ubuntu & RHEL. I also want to extend it to build/test/release stable branches. The current whenjobs script is attached. Rich.

KVM Image not working after expansion

by vipul borikar

Hello, I expanded a KVM image of 4gb to 10 gb .... My Host machine is RHEL 6.1 and Guest is RHEL 5.5 Command i used is: virt-resize --expand /dev/sda1 RHEL5.5-64bit.img RHEL5.5-10gb Commands successfully gets executed... Old disk works fine i mean it boots properly but the new disk stucks at GRUB... Has any one seen this behavior... What should i do to debug this problem.. -- Thanks Vipul Borikar "Our task must be to free ourselves...by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty."

[PATCH 0/4] Add various ntfs* tools and unify label setting.

by Richard W.M. Jones

This miscellaneous patch adds bindings for: - ntfsfix - ntfsclone - ntfslabel and unifies filesystem label setting through a single API 'set-label' which replaces 'set-e2label' and is also able to set labels on NTFS using the ntfslabel program. 'ntfsfix' has been added as a possible way to fix RHBZ#797760. However I have not found a way to fully fix this bug. See discussion in the bug. 'ntfsclone-in' and 'ntfsclone-out' have been added at the request of a user. Rich.
