The live migration of this VM still has to be tested - you may need to copy/clone the disk image to get it into VHD format... | The live migration of this VM still has to be tested - you may need to copy/clone the disk image to get it into VHD format... | ||

| + | == Wrong VM type - or resetting the boot loader == | ||
| + | |||
| + | === Set the VM image type to PV === | ||
| + | |||
| + | The HVM configuration of a VM is obtained (via the CLI) using | ||
| + | xe vm-param-list uuid= | ||
| + | where the uid is obtained using <tt>xe vm-list</tt>. The HVM configuration looks like: | ||
| + | HVM-boot-policy ( RW): BIOS order | ||
| + | HVM-boot-params (MRW): order: cn | ||
| + | HVM-shadow-multiplier ( RW): 1.000 | ||
| + | PV-kernel ( RW): | ||
| + | PV-ramdisk ( RW): | ||
| + | PV-args ( RW): | ||
| + | PV-legacy-args ( RW): | ||
| + | PV-bootloader ( RW): | ||
| + | PV-bootloader-args ( RW): | ||
| + | |||
| + | but we want to clear the HVM settings amd make it boot PV via pygrub. Try | ||
| + | xe vm-param-set uuid=<vm uuid> HVM-boot-policy="" ''(clear the HVM boot mode)'' | ||
| + | xe vm-param-set uuid=<vm uuid> PV-bootloader=pygrub ''(set pygrub as the boot loader)'' | ||
| + | xe vm-param-set uuid=<vm uuid> PV-args="console=tty0 xencons=tty" ''(set the display arguments)'' | ||
| + | Other possible options are: �console=hvc0 xencons=hvc� or �console=tty0� or �console=hvc0�. | ||
| + | |||
| + | Followed by | ||
| + | xe vm-disk-list uuid=<vm uuid> ''(this is to discover the UUID of the interface of the virtual disk)'' | ||
| + | xe vbd-param-set uuid=<vbd uuid> bootable=true ''(this sets the disk device as bootable)'' | ||
