Recompiled /usr/lib/xen/boot/hvmloader - includes INT13 LBA48
Replacement Xen HVM romBIOS which support INT13 LBA48 extensions to correctly calculate drive geometry for disks/images larger than 128GB (should work with disks of up to 2TB (2048GB)).
Compiled from SRPM: xen-3.0.3-64.el5_2.9
Directions of use:
replace existing /usr/lib/xen/boot/hvmloader file and create domU
Notes:
Pretty sure this is platform independent as the domU instance is already
being virtualised at this stage.
I have tested this patch and it's working fine in Xen HVMBIOS although initially my machine saw only 16G disk and finally after applying this patch it was able to see 400G disk. I have formatted and mounted it and `df` showed me size of 400G in total. All disk I/O operations I tried were working fine, no problems occured at all. Michal Fix built into xen-3.0.3-84.el5 Verified on xen-3.0.3-91.el5 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below.
