Partition first, then install grub |

PV does not supply a "BIOS", which means, Grub is not used. |

Most PVs are done that way. |

If using HVM, then yes. |

If using PV, then up to you. |

Which features are you missing that native partitions have? |
| 36 |
|
| 37 |
Most Xen hosts use LVM. |

LVM for partitions |
| 42 |
Pass LVs to Xen domains |
| 43 |
For PV: Store kernel on Host and point to the kernel in the domain config. |
| 44 |
For HVM: pretend it's a physical box |

When using PV, no. (And that's got nothing to do with the CPU architecture.) |
