I''m using the CentOS 6 bundle of xen from http://dev.centos.org/centos/6/xen-c6/ and ran into an issue when creating domains with multiple VHD tap disks. Comparing unstable to the 4.2.1 code I''m using, it seems this issue still applies. I''m using a configuration line that looks something like disk = [

This is v3 of my disk series. What were previously patches 01-06 have been applied. These are the tested and updated remainder, addressing the previous comments. 1 Preparatory work. 2-4 The new parser and its documentation. 5-6 Replace old parsers with calls to the new one. 7-8 Two features, one of them essential. 9 Basic test suite for disk string parsing, as adhoc script.

This patch series provides the facility to eject and insert a cdrom when the used device-model is qemu-xen. The only difference between both device-model is a call to a QMP command as `xl cd-insert ...` will still update xenstore, even if it''s not used by QEMU.

Hi, List, I''m trying xl create a pv guest with qcow/qcow2 image, it always fails at libxl_device_disk_local_attach. #xl create pv_config_file libxl: error: libxl.c:1119:libxl_device_disk_local_attach: cannot locally attach a qdisk image if the format is not raw libxl: error: libxl_create.c:467:do_domain_create: failed to run bootloader: -3 disk configuration is: disk=[

Hi, I am doing some experimentation with xen and Ceph and have a problem booting my guest when my disk = [] uses an alternate block script. Installation from a .iso was ok since the boot device was a file but now trying to boot from the rbd neither the hvmbuilder or pygrub can start as they treat the first value after target= as the /dev node to try and use. My disk parameter looks like: disk =

I think I posted this patch before, but it looks like it was in December 2012 (!). 1/1 libxl: introduce an option for disabling the non-O_DIRECT workaround Ideally it would go into 4.4, at least. Provided the corresponding qemu part has gone into qemu-xen, which I think it has. Can anyone confirm ?
