Paigaldamine - Proxmox virtuaalne arvuti
Väited
- VPP tarkvara paigaldatakse https://packagecloud.com/ repositooriumist
- 2024 aasta suvel on kõige värskem toetatud Ubuntu operatsioonisüsteemi versioon 22.04
- paigaldusjuhend asub aadressil https://s3-docs.fd.io/vpp/24.06/gettingstarted/installing/ubuntu.html
- secure boot parem välja lülitada, vastasel korral saab vpp paigaldamisel dmesg selliseid teateid
[ 162.223607] Lockdown: vpp: raw io port access is restricted; see man kernel_lockdown.7
Virtuaalne arvuti peab toetama 2M suurust hugepagendust ja 1024 tükki, nt sobib sellise seadistusega virtuaalne arvuti
root@pve-moraal-x570:~# cat /etc/pve/qemu-server/9911.conf agent: 1 bios: ovmf boot: order=virtio0;ide2;net0 cores: 4 cpu: host efidisk0: sn_srv_btrfs:9911/vm-9911-disk-0.raw,efitype=4m,pre-enrolled-keys=1,size=528K ide2: none,media=cdrom machine: q35 memory: 8192 meta: creation-qemu=7.1.0,ctime=1674411406 name: ubuntu-2204-vpp-01 net0: virtio=BC:24:11:9B:C3:E4,bridge=vmbr1,firewall=1,tag=111 numa: 1 ostype: l26 parent: enne-vpp-katset-puhas scsihw: virtio-scsi-single smbios1: uuid=174e8d69-5f6e-4296-8bd4-73e7247dae1e sockets: 1 vga: virtio virtio0: sn_srv_btrfs:9911/vm-9911-disk-1.raw,iothread=1,size=20G virtio1: sn_srv_btrfs:9911/vm-9911-disk-2.raw,iothread=1,size=2G vmgenid: 8de853d2-a9eb-4888-a3c6-b36d13896a96
ning kerneli rida
root@ubuntu-2204-vpp-01:~/20240813# cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-5.15.0-118-generic root=/dev/mapper/system-root ro default_hugepagesz=2M hugepagesz=2M hugepages=2048
kus
- tundub, et numa: 1 ega kerneli hugepages osakond ei ole tegelikult vajalik
- host cpu tüüp on vajalik
apt repo seadistuse lisamiseks sobib avada https://packagecloud.io/fdio/release ning pressida nupul 'Debian', tulemusena pakutakse kopeerida selline käsk
# curl -s https://packagecloud.io/install/repositories/fdio/release/script.deb.sh | bash
käsu andmise tulemusena tekitatakse muu hulgas nt selline apt seadistus Ubuntu 22.04 puhul
# ls -ld /etc/apt/sources.list.d/fdio_release.list /etc/apt/keyrings/fdio_release-archive-keyring.gpg -rw-r--r-- 1 root root 2823 Aug 12 22:26 /etc/apt/keyrings/fdio_release-archive-keyring.gpg -rw-r--r-- 1 root root 357 Aug 12 22:26 /etc/apt/sources.list.d/fdio_release.list # cat /etc/apt/sources.list.d/fdio_release.list deb [signed-by=/etc/apt/keyrings/fdio_release-archive-keyring.gpg] https://packagecloud.io/fdio/release/ubuntu/ jammy main deb-src [signed-by=/etc/apt/keyrings/fdio_release-archive-keyring.gpg] https://packagecloud.io/fdio/release/ubuntu/ jammy mai
