Dear Boris,
 
 
 
I have changed my opensolaris vm configuration. Please see

I see my OpenSolaris guest sending DHCPDISCOVER and my OpenSUSE 11.1 
32-bit Dom 0 Xen host sending DHCPOFFER but the OpenSolaris virtual machine 
is not setting the offered dynamic IP address to it's virtual NIC.

              Does your OpenSuse 11.1 
32-bit has static IP address or it obtain it via DHCP ?

At the moment there is only one network card installed on my lab PC in my 
company running OpenSUSE 11.1 32-bit with Xen 3.4.1-rc8 Dom 0 kernel 
2.6.30-rc6 (jeremy). So when there are more network cards installed, there 
will be eth0, eth1, eth2 ethernet bridges, etc.
                   
                    Then I can assign the virtual network card in each 
virtual machine to a specific ethernet network bridge (out of many bridges) 
in Domain 0 using the vif command in guest domain configuration.

Dear Boris,
                   
                    The ethernet network bridge on OpenSUSE 11.1 is

This means that OSOL 
installer (by default ) will issue DHCPDISCOVER via your Xen bridge, looking 
for DHCP server on your LAN. Only on RHEL 5.3
                        (F10 with Xen 3.3.1 src.rpm been installed 
along with generated packages) with libvirtd & dnsmasq up and running 
you can specify
                         vif=['bridge=virbr0' ] to detect DHCP 
Server at your Dom0.
                       
                        View for instance :-
                        
http://bderzhavets.wordpress.com/2009/05/07/backport-zfs-support-to-xen-331-f10-dom0-kernel-2630-rc3-tip/
                       
                        I don't have any experience with OpenSuse 11.1 
. I hardly remind they tried to reproduce RH's technology. Most probably 
they did it in SLES 11 (not sure). Check for libvirtd&dnsmasq daemons up 
and running.
                        But if your OpenSuse 11.1 Dom0 is on "dhcp" 
bridge itself , then no problems. Just vif=['bridge=eth0'].
                       
                        Boris.

Dear Boris,
                         
                          This means I have to install a DHCP server or 
dnsmasq in my Dom 0, listening on my Dom 0's IP address, so that it can 
assign dynamic IP addresses to the DomU.
                         
                          By the way, are there any paravirtualized 
device drivers that I can install in DomU to improve the performance of the 
virtual machine?
                         
                          Thank you.

                              let me know. It might happen and requires

                                     Teo, it 
is up to you how to manage, if you just having fun.
                                        Otherwise, downloading 64-bit 
OpenSuse 11.1 ISO image
                                        takes just 12-14 hr even at 
slow ADSL speed ( like 100 KB/sec).
                                        Install takes 30 minutes and 
brings you to the trusted results, instead
                                        of wasting a lot of time in 
case of business environment assignment.
                                        Pasi has 32-bit experience due 
to hardware limitations, which you don't
                                        have.

My colleague installed OpenSUSE 11.1 32-bit on the Core 2 Duo machine in our 
labs. Please see my earlier replies in the same topic.  
                                         
                                       
                                      
                                      
                                        
I was too lazy to reformat and install 64-bit OpenSUSE, so I proceeded with 
Xen Dom 0 pvops kernel compilation on 32-bit Linux host.  
                                         
                                       
                                      
                                      
                                        
I admit I am getting a lot of headache. Haha.

Once again, i don't see any reason to to run 32-bit OS on Core2Duo,
                                                unless you like Xen 
head ache. Core development (PVOPS) is obviously
                                                running in 64-bit 
environment.

                                                      That is not 
supposed to happen. I would suggest clean OS (without any built in xen 
presence) install , followed by  Xen 3.4.1+pvops kernel clean install.

I am very puzzled. In investigating the cause of the sudden 
success of the CentOS 4.7 32-bit PV guest being able to run, I have 
uninstalled virt-manager and all of its dependencies:  
                                                       
                                                     
                                                    
                                                    
                                                    
                                                    
                                                    
                                                    
                                                    
                                                    
                                                    
                                                    
                                                    
                                                      
Then I proceeded to "make uninstall" in xen-3.4-testing source 
tree, which also removed my self compiled Xen Dom 0 pvops enabled kernel, 
initrd and kernel modules.  
                                                       
                                                     
                                                    
                                                    
                                                      
After doing the above, I re-installed back the Xen hypervisor, 
libraries and tools, and also the kernel, initrd, and modules. Then I 
proceeded to reboot my machine. After rebooting, my CentOS 4.7 32-bit PV 
guest is still able to start and run!  
                                                       
                                                     
                                                    
                                                    
                                                      
I am still very puzzled! What causes the PV guest initially cannot 
start? Then what subsequently causes the PV guest to suddenly be able to 
start and run???  
                                                       
                                                     
                                                    
                                                    
                                                    
                                                    
                                                      
Anyway my CentOS 4.7 guest domain is now running. I shall now 
proceed to virtualize OpenSolaris 2009.06.

                                                        It's very strange. Suddenly my CentOS 4.7 
32-bit PV guest is able to start!!! Previously it refuses to start at all. 
 
                                                         
                                                       
                                                      
                                                      
                                                        I think I must have changed something in Dom 0 
when I attempted "yast --install virt-manager". This action might have 
solved the problem. When I tried to install virt-manager, it also tries to 
install xen-libs-3.3.1 and xen-tools-3.3.1 as dependencies. However, I 
started off my Xen Dom 0 pvops kernel install with Xen 3.4.1 rc8 branch. 
 
                                                         
                                                       
                                                      
                                                      
                                                        I need to investigate more why suddenly my 
CentOS 4.7 32-bit PV guest is able to start.

Re: Re[8]: [Xen-devel] Unable to Configure Xen Dom 0 in Jeremy's PVOPS 
Kernel  
                                                         
                                                        
                                                        
                                                        
                                                          I realized that Fedora 10 32-bit anaconda 
installer does not install PAE kernel after mounting the guest disk image 
file. I mounted the guest disk image file using losetup and kpartx which 
adds device nodes to /dev/mapper. I examined the /boot directory after 
mounting the guest disk image file and found no PAE vmlinuz and initrd. 
 
                                                           
                                                         
                                                        
                                                        
                                                          Still using the mounted Fedora 10 32-bit guest 
disk image file, I changed root to the guest disk filesystems and attempted 
to install the PAE kernel. Then I modified menu.lst to boot the PAE kernel. 
After modifying the grub configuration of the guest domain, I un-mounted the 
guest filesystem.  
                                                           
                                                         
                                                        
                                                        
                                                          I proceeded to boot the F10 32-bit guest, since 
I changed to PAE kernel. It is able to boot now (since the PAE kernel is 
xen-aware) but then it complains cannot mount /dev/root. Probably something 
to do with the PAE initrd file.
