Problem with sunvdc driver in Solaris 11 LDOM installation
Hi everyone, this is my first post to this list so please be kind with me... :-) I tried to install Debian sparc 7.4.0 in a Solaris LDOM. Because i am behind a corporate firewall the network install was no option. When i tried to mount the cdrom after modprobing sunvdc i recognize in dmesg that all the iso-images Solaris exports as virtualized CD/DVD drives are _exactly_ 640MB even if its a DVD.iso. With the hard disk images exported as virtualized HDDs this is not the case. So my workaround was to copy all the iso image contents on a HDD image and install from there. 1. Can anybody confirm this (or is this even a known bug? i didnt find anything on Google though). 2. If it is a Bug, where is the appropriate location to raise it? Thanks in advance, Claas Ziemke p.s. i can post dmesg output etc. of-course, just didnt want to spam the list with my first post :-) -- ESA - European Space Agency Claas Ziemke Young Graduate Trainee Software Systems Division | TEC-SWG ESTEC Keplerlaan 1, PO Box 299 NL-2200 AG Noordwijk, The Netherlands Room Ef232 claas.zie...@esa.int | www.esa.int T +31 71 565 8759 This message and any attachments are intended for the use of the addressee or addressees only.

Re: Problem with sunvdc driver in Solaris 11 LDOM installation
Hi Patrick, thx for the quick answer. The good news is i can confirm that [1] is wrong for my combination (Netra SPARC T4-1 + Solaris 11 + Debian 7.4.0) it _is_ usable. I checked the LDOM by installing Solaris in it, it works, so the problem is either a Linux only problem or a problem with the specific LDOM/Linux combination. (What i really suspect is a combination of LDOM/sunvdc driver/partition tables). Yeah i guess i have to go to the maintainer directly. I gonna try the lkml and see if i can help with testing at least... ( always wanted to contribute a patch in the kernel too :-) ) Gonna keep you posted.

I think LDOMs are poorly supported by Debian and perhaps Linux in general. If you search debian sparc ldom in Google, there are a hits about various problems, but one statement [1] in particular sums up what I thought: current state of linux in LDOMs currently is unusable. I'm actually surprised that you managed to get it installed at all. That's cool. I'm not 100% sure where you should raise a bug, but Linux sparc kernel mailing list might be a better place for a driver issue. As a different question, if you have Solaris installed into an LDOM, does it report the correct size for the same disk? That is -- is there a problem with the LDOM software and ISO images, or is there a problem with the Linux driver -- being certain of that would also be really helpful for the kernel developers.
