Description Mark McLoughlin 2009-02-06 14:24:42 UTC 
If I create a new qcow2 file and try and install Fedora 8 on it, the installer never shows sda in the partitioning screen. anaconda.log shows:

  removing drive sda from disk lists; adding to skip list

Turns out this isn't a problem with kvm-83 from git, so I added some debugging to block-rw-range-check.patch:

+    if (ret)
+      printf("Failing bdrv_rd_badreq_sectors(%ld, %d) : total_sectors = %ld\n",
+             sector_num, nb_sectors, bs->total_sectors);

and I see:

  Failing bdrv_rd_badreq_sectors(192, 1) : total_sectors = 192

Reproduced here. Investigating.
Comment 2 Eduardo Habkost 2009-02-11 13:17:46 UTC 
Found the issue: the patch on Rawhide is using bdrv_rd_badreq_sectors() instead of bdrv_rw_badreq_sectors() on bdrv_aio_write().
Comment 3 Eduardo Habkost 2009-02-11 13:36:55 UTC 
Fixed on Rawhide CVS (kvm-83-4.fc11)
Comment 4 Daniel Berrangé 2009-03-11 12:40:14 UTC 
Reassigning: The kvm package no longer exists in rawhide/F11, since it is now part of 'qemu'.
Comment 5 Daniel Berrangé 2009-03-16 12:52:49 UTC 
Fix is present in new merged RPM qemu-0.10-0.9.kvm20090310git.fc11.x86_64

Tested in F11beta and qemu-kvm could recognize the hard drive.

Thanks
