Debian install via ISO for Virtualizor

Arirang

Hi.

If you install Debian via ISO in Virtualizor, it's irritating.
I do some steps after ISO install. There may be better ways.

---

Logging through VNC.

Grub Update
open file /etc/default/grub
find this line GRUB_CMDLINE_LINUX="" and change to

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0" 

and apply changes.

update-grub

I usually prefer vim, but without installing vim, using default vi is difficult to use. so I use nano.

Remove Swap
open /etc/fstab
You can see the device CD-ROM used for installing.
Remove that line. If you don't, There is an error "gave up waiting for suspend resume device debian" taking long time when booting up

Network Configuration

If your gateway configuration is like below, change it. ipv6 as well.
post-up, ip doesn't work well. I don't know why.

auto eth0
iface eth0 inet static
    address 1.1.1.101
    netmask 255.255.255.0
        post-up route add 1.1.1.1 dev eth0 
       post-up route add default gw 1.1.1.1 dev eth0 

to

auto eth0
iface eth0 inet static
    address 1.1.1.101
    netmask 255.255.255.0
    gateway 1.1.1.1

Some provider changes your network configuration if you reboot from Virtualizor panel.
As far as I know, there is no way clients is able to disable.

So change file attribute so that Virtualizor cannot modify them.

sudo chattr +i /etc/network/interfaces

If you need to change it later, remove that

sudo chattr -i /etc/network/interfaces

Final Step : reboot
