If yes ( md0 : active raid1 sda2 sdb2), unmount the RAID and stop it:.
#QEMU BOOT ISO SOFTWARE#
Check if the server has any software RAID:.It’s not strictly necessary as most installers can repartition, but this way we can handle any RAID / mounting issues right away. Now that we’re in rescue mode, we can wipe the disks clean before installing. # ssh As we can see, rescue mode is a Debian-based image: Once up, we receive a mail with SSH credentials and can log in.Switch to rescue mode from the Boot / Netboot menu.Go to the web GUI of the dedicated server.This should work on both OVH, SoYouStart, and Kimsufi.
#QEMU BOOT ISO ISO#
Since SoYouStart is basically retired OVH hardware, some of their servers now have IPMI as well, and I expect so will Kimsufi over time.īut if IPMI is unavailable (or doesn’t work because of Java shenanigans) and we don’t want to pay for KVM IP, one solution is to boot an ISO image from rescue mode via QEMU KVM.
#QEMU BOOT ISO INSTALL#
One trick is to use IPMI, available on most servers at OVH and allowing to install an ISO image. partition scheme or executing a post-install script), but we’re out of luck if we need anything special – another operating system, a specific filesystem, etc. When spinning up a dedicated server, we can pick from installation templates tweakable to some extent (e.g. SoYouStart, for good hardware on a reasonable budget.OVH itself, targeting high-end and enterprises willing to pay top $$$.Is there an approach with virtualization.It’s been several years now that OVH offers dedicated hosting under 3 brands: It looks like there were similar issues in this thread from someone trying to boot from the installation ISO. Press oneį) to start an interactive shell having pid 1 (needed if you want to Root filesystem on `/mnt-root' and then start stage 2.

However, I was looking at all the nifty tools under virtualisation and wondering if that might be doable as well. drive media=cdrom,file=rescue.iso,format=raw,readonly=on \
I’m able to boot the image with qemu directly, and I’m sure I could just do something like I’ve done in another flake to wrap a script around qemu and get the job done: qemu-system-x86_64 \ However, I’m having trouble using the user-friendly virtualisation.* tools, in part due to it being a read-only root (which fsk doesn’t like). Now I’m trying to add an additional flake output to run the ISO as a virtual image as part of testing. It’s coming along pretty well! GitHub - n8henrie/nixos-rescue: NixOS-based USB rescue image I’m making a little nixos-based ISO image as a USB rescue image – something I think NixOS is particularly well suited for! I’m hoping to have something that is headless-friendly that will boot straight to a copytoram image (several of my devices have only 1 USB port) that has tools for btrfs, zfs, arch-install-scripts, and several others tools available offline.
