Optical drive not recognized by some Linux 2.6.20 kernels This is a continuation of the thread I started here: http://forums.parallels.com/thread8763.html The problem is essentially that if I boot a Linux virtual machine in Parallels (build 3188) running the newer flavors of kernel version 2.6.20, the virtualized optical drive does not work. I wanted to blame this on Parallels, but the fact is that the optical drive works just fine with early versions of the 2.6.20 kernel and 2.6.19 and lower. So, it must have been a kernel change that caused the problem. I am specifically having the issue in Ubuntu Feisty Herd 5, Ubuntu Feisty Beta, and Fedora 7 test 2 and test 1. I filed a bug report with Ubuntu here: https://launchpad.net/ubuntu/+source....20/+bug/95830 I am hoping it gets looked at since the issue will likely affect other Parallels users who run Linux VMs. Speak up if anyone else has this problem or if you have an Intel Mac to test the problem with. |

I just added a bug report for the Fedora side of things in RedHat's bugzilla. Check it out at: https://bugzilla.redhat.com/bugzilla....cgi?id=233814 I guess now it is time to wait and see if anyone notices. I think I'm going to shoot a quick email to the Parallels team with those bug report links as well. |

Hehe...looks like I wasn't making this up... See these other threads: http://forums.parallels.com/thread10333.html http://forums.parallels.com/thread10297.html Also, there have been updates in both the Fedora and especially the Ubuntu bug reports. Check them out for more info: Fedora: https://bugzilla.redhat.com/bugzilla....cgi?id=233814 Ubuntu: https://launchpad.net/bugs/95830 |

I have the same problem, please fix this! I'm a parallels user since day one (no joke) and I've also pre ordered it during the first beta period. It's a pitty that I now have to install vmware fusion because I need Ubuntu 7 today (University Project). lg philipp |

There is an error into Parallels CDROM emulation ( but may be not error at all) . For those who familar with linux kernel - inquiry command for CDROM comes with zero into Cylinder IDE register. Parallels doesn't like zero value there. It will be fixed into future. I don't know will update comes or release including this fix. So. there is a work around to avoid this checking, simply set VM type as SOLARIS, in this case CDROM will work. But... of couse Ubuntu may work unstable or even fails. Because incorrect OS type is set. Anyway I succesfully booted Ubuntu 7.04 This also true for Fedora Core 7 (As I've seen error log here https://bugs.launchpad.net/ubuntu/+s....20/+bug/95830) I've checked it more , all commands come with zero into Cylinder IDE register, so It will be fixed surely. |

Installing Ubuntu 7.04 on Parallels success here is what I did as suggested by the user mmika before me, select solaris as your machine and then boot and install. when you are done just click on the configuration of the virtual machine and change it back to linux. boot at you will see it will take a bit and then give you a login screen. hope this helps good luck |
