Muudatus seisneb virtuaalsele arvutile täiendava nö esimese plokkseadme lisamisel, suurusega 1 G. Sinna moodustatakse gpt partitsioonitabel ning vfat failisüsteem, ja ta vastab nö kataloogile /boot/efi, sinna ta ka monteeritakse kokkuvõttes. Juurfailisüsteem ja muu jääb sinna kus ta seni on olnud. Oluline on, et muudatuse käigus ei muudeta olemasoleva plokkseadme partitsioonitabelit ega lvm vms, st ebaõnnestumisel saab pöörduda tagasi kergesti (varundus peaks aga siiski olema olemas).

====Boot Order märkused====
  +
  +
PVE webgui Boot Order määrab kaks
  +
  +
* millised plokkseadmed osalevad uefi faasis
  +
* millised järjekorras plokkseadmed osalevad uefi faasis alglaadimisel
  +
  +
Kui on linnutatud ainult üks seade
  +
  +
[[Fail:20260516-from-bios-to-uefi-05.png|800px]]

  +
Kui on linnutatud ainult kaks seadet
  +
  +
[[Fail:20260516-from-bios-to-uefi-04.png|800px]]
  +
  +
Antud juhul on see väga oluline kuna grub alglaadur on kahel seadmel laiali
  +
  +
* grub.efi rakendus asub /dev/vdb
  +
* grub.conf seadistus asub /dev/vda
  +
  +
Kui Boot Order on linnutatud vaid /dev/vda, siis peatub arvuti käivitumine 'grub>' prompt juures. Selles mõttes võiks olla PVE webgui osakonna nimeks nt 'UEFI device visibility and Boot Order'.
  +
  +
===Üle vsock ssh kasutamine===
  +
  +
Osutub, et uuemal ajal, st PVE v. 9, Debian v. 13 virtuaalne avuti on võimalik PVE host pealt pöörduda guest poole üle ssh kasutades vsock protokolli (mitte tavalist tcp/ip protokollil põhinevat võrku). Selleks tuleb virtuaalsele arvutile lisada PVE platvormi poolt vsock tugi

  +
<pre>
  +

  +

  +
</pre>
  +
  +
ja virtuaalsel arvutil peab olema tarkvaraline vsock tugi. Nt Debian v. 13 puhul on sshd serverisse see integreeritud

Virtuaalse arvuti vaatest andmetega tegelemine 

pve virtuaalne arvuti -> pve füüsiline arvuti -> over-iscsi-zfs-storage-server

Sõltuvalt qemu virtuaalse arvuti virtuaalse plokkseadme 'Cache' seadistustest on võimalik erinevate cache komplektide-kombinatsioonide kasutamine andmete liikumisel virtuaalses arvutis töötava protsessi juurest zfs storage serveri füüsilisele plokkseadmele. Tundub, et 2025 aastal on kõige keskmisemale kasutusele sobiv valik 'Cache: nocache'

  • hea jõudlus
  • hea terviklus

Andmete liikumise teekond

  • virtuaalse arvuti rakendus
  • virtuaalse arvuti vfs failisüsteem
  • virtuaalse arvuti page cache (vfs'ga seotud)
  • virtuaalse arvuti ext4 failisüsteem (ext4 draiver)
  • virtuaalse arvuti lvm
  • virtuaalse arvuti fdisk partitsioonid
  • virtuaalse arvuti virtuaalne sata vms kontroller
  • füüsilise arvuti qemu protsess
  • füüsilise arvuti open-iscsi poolt teostatud /dev/sda scsi plokkseade (puudub cache)
  • füüsilises arvutis storage'ga seotud cache puudub
  • storage arvuti targetcli (puutub cache)
  • storage arvuti zfs ressurss (sisaldab zfs cache)
  • storage avuti füüsilise plokkseadme controller-cache

'Cache: nocache' parameeter on üks vähestest parameetritest, mis avaldab mõju nö mõlemas suunas

  • virtuaalse arvuti seest kasutada olevale storage ressursile
  • kuidas füüsilise arvuti sees virtuaalsele arvutile vastav qemu protsess kasutab allolevat plokkseadet

Käesolevas tekstis kirjeldatakse nelja komponendi seadistamist

  • virtuaalsele arvutile vastav qemu protsess
  • iscsi initiator
  • iscsi target
  • zfs lahendus

zfs lahendus iscsi target arvutis

Füüsilised kettad on kasutusel nö kõige tavalisemal viisil, eriti tähendab see, et ketastel on sisselülitatud nö tavaline controller-cache 

root@pve-svc-02:~# lsscsi -s | grep 4.00T

zfs cache töötab tavalisel viisil, st on sisse lülitatud olekus, nt 

root@pve-svc-02:~# zfs get all | grep -i cache | grep vm-106-disk-0
zp_crucial_mx_4/vm-106-disk-0     primarycache          all                     default
zp_crucial_mx_4/vm-106-disk-0     secondarycache        all                     default

targetcli iscsi target arvutis

targetcli seadistamine koosneb kahest tegevusest

  • zfs põhise alus-storage storage publitseerimine
  • publitseerimisel sobivalt scsi protokolli parameetrite kasutamine (eriti cache, sparse jms esitamine)

BIOS arvuti teisendamine UEFI arvutiks

Tööpõhimõte

Peamised kaalutlused BIOS arvuti teisendamisel UEFI arvutiks

  • vajadus saada osa secure boot lahendusega kaasnevast turvalisusest
  • nö täieline reinstall oleks liiga aeganõudev, kohmakas jne

Muudatus seisneb virtuaalsele arvutile täiendava nö esimese plokkseadme lisamisel, suurusega 1 G. Sinna moodustatakse gpt partitsioonitabel ning vfat failisüsteem, ja ta vastab nö kataloogile /boot/efi, sinna ta ka monteeritakse kokkuvõttes. Juurfailisüsteem ja muu jääb sinna kus ta seni on olnud. Oluline on, et muudatuse käigus ei muudeta olemasoleva plokkseadme partitsioonitabelit ega lvm vms, st ebaõnnestumisel saab pöörduda tagasi kergesti (varundus peaks aga siiski olema olemas).

Muudatuse protseduur

Enne muudatust paistab virtuaalne arvuti selline

20260516-from-bios-to-uefi-01.png

ning 

# df -T -h -t ext4
Failisüsteem                      Tüüp  Maht Kasut  Vaba Kas% Haagitud

/dev/vda1                         ext4  462M  325M  109M  75% /boot

Lisatakse töötavale arvutile 1 g plokkseade 

Hardware -> Add disk -> ...

Veendutakse, mis on konkreetsel juhtumil 1 g lisatud plokkseadme nimi, nt 

# fdisk /dev/vdb -l
Disk /dev/vdb: 1 GiB, 1073741824 bytes, 2097152 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

edasi käsundamine 

# apt-get install parted

# parted /dev/vdb mklabel gpt
# parted /dev/vdb mkpart primary fat32 1MiB 100%
# parted /dev/vdb set 1 esp on
# mkfs.vfat -F 32 /dev/vdb1
# mkdir -p /boot/efi
# blkid /dev/vdb1

Muuta /etc/fstab faili, st lisada üks rida olemaoleva /boot rea alla, uuid on mitte partitsiooni, aga vfat failisüsteemi 

# cat /etc/fstab
..
UUID=XXXX-XXXX  /boot/efi       vfat    defaults        0       2

Lisada paketid 

# systemctl daemon-reload
# mount /boot/efi
# apt update
# apt install grub-efi-amd64-signed shim-signed mokutil
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=debian --removable
# update-grub

tulemusena

Õeldakse virtuaalsele arvutile poweroff ja muudetakse seadistusi

  • lisatakse 'EFI Disk' (virtuaalne efi riistvara seadistuste salvestamine jms)
  • muudetakse bios -> uefi
  • muudetakse chipset i440fx -> q35
  • muudetakse display default -> virtio-gpu

Peale muudatust paistab virtuaalne arvuti selline

20260516-from-bios-to-uefi-02.png

Lisaks on boot järjekorra seadmed muudetud

20260516-from-bios-to-uefi-03.png

kus

  • tingimata vajalik on virtio1 ja virtio0 - esimesel on bootload ja grub.cfg lühike konf, teisel on konfi sisuline osa

Tulemusena töötab arvuti uefi secure boot režiimis 

# mokutil --sb-state

Kõige lõpus võiks veel öelda, nii tekivad nö naturaalsed efibootmgr ja /boot/efi sissekanded nagu nad oleks seal nö sündinud-uefi'na arvutil

Boot Order märkused

PVE webgui Boot Order määrab kaks

  • millised plokkseadmed osalevad uefi faasis
  • millised järjekorras plokkseadmed osalevad uefi faasis alglaadimisel

Kui on linnutatud ainult üks seade

20260516-from-bios-to-uefi-05.png

Kui on linnutatud ainult kaks seadet

20260516-from-bios-to-uefi-04.png

Antud juhul on see väga oluline kuna grub alglaadur on kahel seadmel laiali

  • grub.efi rakendus asub /dev/vdb
  • grub.conf seadistus asub /dev/vda

Kui Boot Order on linnutatud vaid /dev/vda, siis peatub arvuti käivitumine 'grub>' prompt juures. Selles mõttes võiks olla PVE webgui osakonna nimeks nt 'UEFI device visibility and Boot Order'.

Üle vsock ssh kasutamine

Osutub, et uuemal ajal, st PVE v. 9, Debian v. 13 virtuaalne avuti on võimalik PVE host pealt pöörduda guest poole üle ssh kasutades vsock protokolli (mitte tavalist tcp/ip protokollil põhinevat võrku). Selleks tuleb virtuaalsele arvutile lisada PVE platvormi poolt vsock tugi 

root@pve-wrx90e:~# head -n 1 /etc/pve/qemu-server/50056.conf
args: -device vhost-vsock-pci,guest-cid=50056

ja virtuaalsel arvutil peab olema tarkvaraline vsock tugi. Nt Debian v. 13 puhul on sshd serverisse see integreeritud 

root@unifi-oss:~# systemctl | grep ssh
