Re: [Qemu-devel] Illumos/SmarOS support

Something went wrong with your reply... While it contains a quote it
does not reference the mail you replied to, that way messages get lost
among the constant chatter on qemu-devel.

At FOSDEM, I talked to a Bryant from illumos who wanted to forward my
business card to their KVM/QEMU guys re upstreaming, but I haven't heard
back from anyone so far.

Same as on Solaris 10. There was some alternative trick to "glom"
objects together to avoid linking in that extra object, don't remember
exactly. Hopefully there's an archive of the old Sun blogs somewhere.


Concerning KVM, there was some resentment on the Red Hat side againt the
SmartOS KVM port due to the legal issue of whether GPL'ed KVM may be
combined with CDDL. But that is independent of currently broken QEMU
host support in userland.
