Public bug reported: I report also here some useful informations to improve xen packages and hvm domUs support with xen 4.4 that I already reported on debian bugtracker:
" I advice maintainers for fast and easy improve hvm domUs support on xen debian packages when the xen 4.4 will be packaged to specifying seabios and qemu binary of debian packages from configure, see these patches for details: http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=5c7cbadaccca8dbb47f2c42ab1b5a8afac9275e3 http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=906677d6411c3dc579e07967d0137a12392ff314 Already tested and working with debian packages of qemu and seabios. Also the use of new ./configure ... --enable-qemu-traditional=no can be useful to disable qemu traditional without debian patches. Is possible to specify ovmf binary for experimental uefi hvm support: http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=6b2029c9a1f6b4cd7585fd537d45233f8dde14b7 but in that case ovmf package should be updated at least to commit 447d264115c476142f884af0be287622cd244423 for good xen support. Probably can be good also to put qemu-system-x86 package as dependency instead of recommended. " Tell me if there are other important things that you would into upstream to improve the implementation of xen into the distributions that are not already been made and if I have time I'll try to make them. I also did a large test with upstream qemu and qdisk instead qemu traditional with blktap2 and I saw generic hvm beckmark increase up to 40-60% and disks performance with qdisks and recent upstream qemu increased by several times, above all in writing operations. I think it is better to inform as much as possible to drop xend already deprecated many xen versions ago and will be removed in xen 4.5. I also think it is better to use more qemu upstream and report any problems, The traditional qemu is now less supported, more difficult to maintain, and some new features are only supported by qemu upstream and will not be implemented in the traditional. I hope this information is helpful and sorry for my bad english. ** Affects: xen (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to xen in Ubuntu. https://bugs.launchpad.net/bugs/1297224 Title: Improve xen packages and hvm domUs support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xen/+bug/1297224/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
