| + | ===== qemu + ubuntu 9.04 Desktop i386 booting problem ===== | ||
| + | ubuntu-9.04-desktop-i386.iso is refusing to boot over qemu. | ||
| + | I am using command line | ||
| + | <code> | ||
| + | qemu -cdrom /var/www/ubuntu-9.04-desktop-i386.iso -net nic -net user | ||
| + | </code> | ||
| + | It gives error gives error : | ||
| + | <code> | ||
| + | [ 3.284007] ..MP-BIOS bug: 8254 timer not connected to IO-APIC | ||
| + | </code> | ||
| + | and freezes.\\ | ||
| + | I am using following version of qemu | ||
| + | <code> | ||
| + | $ qemu | ||
| + | QEMU PC emulator version 0.10.0, Copyright (c) 2003-2008 Fabrice Bellard | ||
| + | </code> | ||
| + | The BIOS number was found | ||
| + | and BIOS version used by qemu is as follows | ||
| + | <code> | ||
| + | QEMU BIOS - build: 08/15/08 | ||
| + | $Revision: 1.209 $date: 2008/06/02 20:08:10$ | ||
| + | </code> | ||
| + | |||
| + | I had to update my qemu to version 0.10.5 then it started working | ||
| + | <code> | ||
| + | $ qemu | ||
| + | QEMU PC emulator version 0.10.5, Copyright (c) 2003-2008 Fabrice Bellard | ||
| + | </code> | ||
| + | ===== SQUASHFS error ===== | ||
| + | |||
| + | I am getting following errors in the process of booting. My guess is, most of these | ||
| + | errors are related to failure of httpfs in providing requested logical block, but I need to confirm this. | ||
| + | <code> | ||
| + | Buffer I/O error on device loop0, logical block 272374 | ||
| + | SQUASHFS error: sb_bread is failed reading block 0x845d5 | ||
| + | SQUASHFS error: unable to read fragment cache block [211696cb] | ||
| + | SQUASHFS error: unable to read page, block 211696cb, size c115 | ||
| + | </code> | ||
| + | I have seen this error before, but if I retry the booting then it works. | ||
| + | But now, I have failed two consecutive time on local webserver, which is quite alarming. | ||
