Steve's Blog

Just a quick note to say I’ve updated Xen to 4.1.2 and my Dom0 linux kernel to 2.6.32.50. They should be automatically updated via yum. Remember to edit your grub.conf correctly after updating the kernel.

Just posted an update to both kernel-xen and the xen packages.

Xen changelog:

* Sun Aug 14 2011 Michael Young – 4.1.1-3
- untrusted guest controlling PCI[E] device can lock up host CPU [CVE-2011-3131]

kernel-xen changelog:

* Fri Aug 19 2011 Steven Haigh
! Note: USB-DVB still seems to be broken.
- commit ‘v2.6.32.45′:
- Linux 2.6.32.45
- powerpc: pseries: Fix kexec on machines with more than 4TB of RAM
- powerpc: Fix device tree claim code
- ALSA: snd-usb-caiaq: Fix keymap for RigKontrol3
- ALSA: timer – Fix Oops at closing slave timer
- net: Compute protocol sequence numbers and fragment IDs using MD5.
- crypto: Move md5_transform to lib/md5.c

Details on how to use these packages and set up a repository are available on the EL6 and Xen howto guide.

Have just finished posting a new kernel-xen to the repo.

Changes:

* Sun Aug 14 2011 Steven Haigh 
- Disabled module creation for USB DVB tuners due to errors on compile. This
  will affect all DVB tuners using the dvb-usb module.
  I would assume most people who run this kernel won't use USB tuners on Dom0.
- Merged in 2.6.32.44

I’ve finally changed my blog theme after what is probably years and years of the same theme. This one is very minimalist – which means fast loading etc. I think its quite good – comments welcome

I’ve done a quick refresh to the Xen packages in my repo to remove an extra repository file from the package which could cause some issues with yum. Its a minor issue – so if you’ve already got 4.1.1-2 installed, just delete the file /etc/yum.repos.d/dom0-kernel.repo and you’ll be set.

I’ve just updated the kernel-xen and xen packages used in my Xen Repos for EL6.

Kernel Changelog:

* Sun Jul 31 2011 Steven Haigh
- Brought kernel config inline with stock EL6 kernels
- Fix: xen/blkback: don’t fail empty barrier requests
- Revert “xen/blkback: When writting barriers set the sector number to zero…”
- blktap: Fix reference to freed struct request.
- Merged in 2.6.32.43
- Fixed minor bug in post-install script modifying yum.conf to recognise
kernel-xen as a kernel package and allow multiple installs.
- Fixed bug not removing generated initramfs when removing kernel-xen pacakge

Xen Changelog:

* Wed Jul 20 2011 Michael Young – 4.1.1-2
- clean up patch to solve a problem with hvmloader compiled with gcc 4.6
