Re: [Xen-users] Picture Tutorial: Installing OpenSolaris 2009.06 UNIX as a PV DomU (Xen 3.5-unstable Pv-Ops Dom0 Kernel 2.6.31.5)

Thank you.

I tried to reboot OpenSolaris PV domU but failed. I have to do a normal boot up of OpenSolaris after the failed reboot. The hostid stays the same.

Regarding "type=ioemu" in vif, I wanted to do an upgrade of the virtual network card from Realtek 100 Mb/s to Intel 82540EM Gigabit, and I happen to find the syntax from the document at Oracle here: http://download.oracle.com/docs/cd/E11081_01/doc/doc.21/e10898/templates.htm

I think ioemu stands for I/O emulation. Can anybody explain ioemu in depth?

I have just installed OpenSolaris UNIX as a domU on my home PC to learn more about the operating system.

I will try out the hostid command to see if the hostid changes between reboots of the domU.

Not the DomID and not the Domu hostname

 

Solaris has internal hostid which can be found with the hostid command.

In Solaris it depends on the MAC address of the NIC.

 

Even if u had static mac address in the DomU config file (under the vif =[ ] parameters, you still have changing hostid with the opensolaris as DomU.

 

This however does not effect the root/ZFS file system - but only other ZFS  zpool. So let say u have a second Zpool name NFS, once u will report the DOMU - you will get error about not be able to mount the NFS zpool.

Hi,

Are you referring to the domain ID of the domU or the hostname of the domU?

That is very cool.

 

I have some question in mind: Did u manage to set the hostid to be the same? even if u reboot the DomU server?

 

In my old tests (under xen 2.6.26 debian with Xen 3.2) I was having problems with opensolaris since the hostid was change every restart. This effects the Zpool ID of the ZFS file system, which gives an error that the zpool has being exported to a different machine so please imported.

 

I wanted to use this on my home under xen - since I find ZFS the best file system at the moment. At least until btrfs will be out
