Re: [Qemu-devel] Solaris (9 and 10) supported on 0.6.1?

[emuls]

Hello,

I install a Solaris 10 (03/05) on couple QEMUs from CVS 0.6.2
(Host FEDORA or CentOS) without huge problems (With or without
IDE patch). I tried both instalation from CD-ROM image and CD
(/dev/cdrom).

Issues:
1. If HOST is LINUX check your kernel (QEMU dont like some kernel
hacks to make LINUX kernel faster). What is your HOST OS ?

2. I found than on very fast mashines, if proccessor is faster
then 2Ghz, time insise Solaris 10 instalation is very deformed.
In places where Solaris must wait by default 30s it waits maximum
only 2 seconds. !!! Have anybody idea why ??? What hardware you
have ?  
I use a couple tricks to make instaltion faster:
1. I use only 125MB of memory on install time of first CD, this
will automaticly switch instalation to text mode. After system
will install first CD, use for next boot and instalaiton of rest
CDs 256MB of memory.

2. I use a network floppy image from
http://www.tools.de/solaris/itu/ and add driver in DCA (mount
floppy image du.ing as fda and press escape on begining of
instalation, after F4 add driver) I configure network in user
mode manualy (DHCP don't put right gateway or / and  DNS ?)
ne2000 driver works OK

3. I use a RAW format for hardrive image, QCOW with compression
is realtively slow if you use a CD image on same disk.

4. If you have a relativly slow proccessor you can in LINUX do:

renice -8 (pid of QEMU) 

It will speed up Solaris 10 instalation
