kvm network problem with Solaris 10u8 guest

kvm network problem with Solaris 10u8 guest

[Harald Dunkel]

Hi folks,

I am trying to run Solaris 10u8 as a guest in kvm (kernel
2.6.33.2). Problem: The virtual network devices don't work
with this Solaris version.

e1000 and pcnet work just by chance, as it seems. I can ping
the guest (even though some packets are lost), but ssh or other
TCP connections don't work.

rtl8139 and ne2k_pci are not even listed by "ifconfig -a" on
the guest.

Solaris 10u6 worked fine (using e1000).

Can anybody reproduce this problem?


Any helpful comment would be highly appreciated. Of course
I would be glad to help to track this down.

ssh to login.

the guest.

Solaris 10u6 worked fine (using the e1000 emulation). Same for
the Linux guests.

Can anybody reproduce this problem?

Does opensolaris exhibit the the same problems?  If so, you can probably 
bisect the driver to find the change that broke the device.  With that 
we can probably deduce if it is the device or driver that is broken, and 
what the issue is.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

I verified this right after Harald posted his original
bugreport against debian qemu-kvm package (*).  No,
opensolaris does NOT shows this bug.

I even tried solaris install image -- sol-10-u8-ga-x86-dvd.iso,
but it works here as far as I can see.  I performed only basic
tests however, -- basically because I just don't remember how
to _use_ solaris (it's been about 10 years ago), and can only
do some telnet/ping/ftp.
