Hi

I'm trying to install CoreOS into a KVM VPS managed by SolusVM.

I managed to boot an iPXE ISO, and boot CoreOS off the internet -- but the resulting machine couldn't see a /dev/sda, only /dev/sr0 (the iPXE image). Does the PXE image have a custom kernel that is missing virtio support?

Is there a recommended way to perform this sort of install? I could try booting off a rescue CD ISO, converting the QEMU CoreOS image to a flat file, and dd-ing that to the disk.

Regards

Donald

Yes, the kernel includes virtio but virtio block devices aren't called sd*, those are SCSI devices. Virtio is vd* I think, check /proc/partitions.

Well, the recommended way is to start from a CoreOS disk image directly but if your provider doesn't support managing disk images directly then yes you are stuck with booting to a rescue system or attaching the volume to another host to write an image to it. The coreos-install script can help with this step. No need to start from the qemu image, just use the plain coreos_production_image.bin so you don't need to convert and it is smaller so you don't need to write as much. The filesystem will be resized to fill your disk on boot.
