Instalacja maszyn wirtualnych z terminala - KVM, virt-install

Mam problem z instalacją nowej maszyny wirtualnej. Kierowałem się wieloma poradnikami i nigdzie nie umiem znaleźć odpowiedzi. Problem w tym, że większość użytkowników zakłada możliwość połączenia się z nową maszyną virtualną przez VNC, czy inny program graficzny. Ja chciałbym tego uniknąć.

System matka - debian 8.2 (jessie)

virt-install --nographics -n debian001x64 --description "Testowy Debian" --ram=2048 --cdrom /var/virt/iso/CentOS-6.7-x86_64-minimal.iso --disk path=/var/virt/machine/debian001x64/debian001x64.raw,bus=virtio,format=raw,cache=none, io=native --os-variant=debianwheezy --vcpus 2 --network bridge=br0,model=virtio --os-type=linuxWARNING CDROM media does not print to the text console by default, so you likely will not see text install output. You might want to use --location.Starting install...Creating domain... | 0 B 00:00Connected to domain debian001x64Escape character is ^]

I na tym instalacja się zatrzymuje. - Ja wiem, pewnie teraz mogę się połączyć przez VNC i dokończyć dzieła, ale chcę w przyszłości robić maszyny wirtualne skryptem i nie chcę się bawić w tryb graficzny. Chyba, że polecicie inne rozwiązanie?

Tutaj kolega łączył się podobnie i wchodził w instalację w trybie tekstowym:
[video]https://youtu.be/nVvHCb-ixF4?t=1296[/video]Mnie natomiast wywala informację, że "CDROM media does not print to the text console by default"

Udało mi się odpalić przy instalacji z sieci:

virt-install --nographics -n debian001x64 --description "Testowy Debian" --ram=2048 --location 'http://mirror.i3d.net/pub/centos/6/os/x86_64/' --disk path=/var/virt/machine/debian001x64/debian001x64.raw,bus=virtio,format=raw,cache=none, io=native --os-variant rhel6 --vcpus 2 --network bridge=br0,model=virtio --os-type=linux --console pty,target_type=serial --extra-args 'console=ttyS0,115200n8 serial'bo tu mogłem użyć "extra-args".

Przy instalacji z ISO tej opcji nie mogłem użyć:

ERROR --extra-args only work if specified with --location. See the man page for examples of using --location with CDROM media

Niestety próbowałem też podpiąć moje iso za pomocą location, ale bezskutecznie. Może źle interpretuję:

The location must be the root directory of an install tree.

Nikt tego nie próbował? Tak banalne, czy tak że nikomu nie chce się odpisywać?

Musisz podać w location ścieżkę do zamontowanego iso.

Też próbowałem

ERROR Error validating install location: Could not find an installable distribution at '/mnt/disk/'
The location must be the root directory of an install tree.

ls /mnt/disk

ls /mnt/disk/
autorun.inf css dists efi g2ldr install isolinux pics README.html README.mirrors.txt README.txt tools
boot debian doc firmware g2ldr.mbr install.amd md5sum.txt pool README.mirrors.html README.source setup.exe win32-loader.ini

Montowałem za pomocą:

mount -o loop /var/virt/iso/debian-stretch-DI-alpha4-amd64-netinst.iso /mnt/disk

Po zamontowaniu dysku:

W katalogu install.amd znalazłem szykane vmlinuz, więc skopiowałem je do /var/virt/DVD/debian/images/pxeboot/vmlinuz
Ponowne odpalenie dało mi:

A więc znalazłem initrd.gz również w katalogu install.amd, rozpakowałem i zmieniłem rozszeżenie na .img, a następnie skopiowałem do /var/virt/DVD/debian/images/pxeboot/initrd.img

Po tym instalacja ruszyła! Połączyłem się konsolą, wybrałem język, opcje klawiatury i nagle pyta mnie o sterowniki do CD-Romu, kórego nie mam... pomijam i:

Brakuje mi pomysłów...

Po anulowaniu instalacji wszedłem do command line by sprawdzić czy jest sieć - w końcu to net install, więc może nie wykrywa sieci i robi problemy. Okazał się, że faktycznie sieci nie ma. Dlatego też ściąnąłem pełne CD z LXDE: http://cdimage.debian.org/debian-cd/8.2 ... e-CD-1.iso przygotowałem je jw. i niestety znów to samo. Czegoś mu brakuje, ale nie wiem jak zdebugować o co mu chodzi.
