[Xen-users] Kernel parameter to emulate hdd, connected to xen vm, as sda and not hda
Hi xen-users, I am having several vm''s which are booting with different kernels: 2.6.31(Suse) and 2.6.32(CentOS). In case with 2.6.31(Suse), the hdd, connected to vm is emulated as hda, with 2.6.32(CetnOS) - as sda. What rules such behaviour? I tried to look through the kernel option, but did not find anything obvious. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Disabled atapi support in:
Device Drivers --->
ATA/ATAPI/MFM/RLL support
and the device started showing as sda in 2.6.31
