Re: [Xen-users] [XCP] - How to create a VM from network install

[David Booher <dbooher@xxxxxxxxx>]

Hi, 

I had the same problem this weekend using Fedora 11 and Fedora 12  DVDs to boot from.  What I did was to locate the kernel and initrd.img on the CD and adjust the VM as follows: 

xe vm-param-set uuid=<vm-uuid> PV-bootloader=pygrub

xe vm-param-set uuid=<vm-uuid> PV-bootloader-args="--kernel /isolunux/vmlinuz --ramdisk=isolinux/initrd.img" 

I placed placed these lines just before the "xe vm-start" command and this got the boot going.  After the install and the first boot from the hard drive, you may have to set the hard disk back to "bootable=yes", detach the cd and take the PV-bootloader-arg line back out: 

Let me know if this helps.

Hi all,

 

is there someone who could share the right steps to create a CentOS 5.4 X86_64 Virtual machine from cli. According to manual I used this:

 

#Create VM

xe vm-install template="CentOS 5.4 x64" new-name-label="Prima" sr-uuid=7f998a60-e435-3ed8-bb00-51480c26cdb5

 

retval: 84730e38-de64-d7a1-9769-13d52c6e0d93

 

#Get disk uuid

xe vbd-list vm-uuid=84730e38-de64-d7a1-9769-13d52c6e0d93 userdevice=0 params=uuid --minimal

 

retval: ec6c3d30-b7f8-0e1f-1110-dfc0cf004683

 

#Set boot= false

xe vbd-param-set uuid=ec6c3d30-b7f8-0e1f-1110-dfc0cf004683 bootable=false

 

#Get cd-list

xe cd-list

 

retval: CentOS-5.4-x86_64-netinstall.iso

 

#Add cd

xe vm-cd-add vm=Prima cd-name="CentOS-5.4-x86_64-netinstall.iso" device=3

 

#Get cdrom uuid

xe vbd-list vm-uuid=84730e38-de64-d7a1-9769-13d52c6e0d93 type=CD params=uuid --minimal

 

retval: e03b58ed-aa43-8475-1f98-2638111dc11b

 

#Set cd boot=true

xe vbd-param-set uuid=e03b58ed-aa43-8475-1f98-2638111dc11b bootable=true

 

#Set default repository

xe vm-param-set uuid=84730e38-de64-d7a1-9769-13d52c6e0d93 other-config:install-repository=cdrom

 

#Start

xe vm-start vm=Prima

 

retval:

The bootloader returned an error

vm: c4add69a-f3bb-7e33-ada7-537e30ce0af7 (Prima)

msg: Error from bootloader: Failed to parse the output of bootloader: ()

 

Thanks for any suggestion/help.

 

Best regards,

Francesco Gallo
