...ad (no idea how to set the boot loader to use that); when I set that on the kernel command line, the kernel crashes during boot with: kernel tried to execute NX-protected page - exploit attempt? (uid: 0) BUG: unable to handle kernel paging request at ffffffff81a4cfec IP: [<ffffffff81a4cfec>] vty_init+0x174/0x174 PGD 18d3067 PUD 18d4063 PMD 3d9e1063 PTE 8000000001a4c163 If I don't do either, I can add a getty on hvc0 with "systemctl enable serial-getty at hvc0.service", but that doesn't get me the boot loader or kernel messages. -- Chris Adams <linux at cmadams.net>

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
