Proxmox ISO 파일 수정하기

OpenStack 환경에서 Proxmox를 설치하는 도중 Installer가 ISO를 인식하지 못하는 오류가 발생하였다

가상화 인터페이스로 VirtIO를 사용하고 있었고, Proxmox가 /sys/block/vd* 를 스캔하지 않기에 발생한 문제다

따라서 Proxmox initrd를 수정해주는 작업을 진행했다

zerglinggo@akane:~/proxmox/boot$ sudo unmkinitramfs initrd.img initramfs
zerglinggo@akane:~/proxmox/boot$ sudo vim initramfs/init

[수정 전]
...
for i in /sys/block/hd* /sys/block/sr* /sys/block/scd* /sys/block/sd* /sys/block/nvme*; do
...

[수정 후]

for i in /sys/block/hd* /sys/block/sr* /sys/block/scd* /sys/block/sd* /sys/block/nvme* /sys/block/vd*; do

zerglinggo@akane:~/proxmox/boot/initramfs$ cd ..
