====== 初始安裝 ======
1,下載
-clear-34500-kvm.img.xz
-OVMF.fd
-OVMF_CODE.fd
-OVMF_VARS.fd
-start_qemu.sh \\
2,unxz clear-34500-kvm.img.xz \\
3,chmod u+x start_qemu.sh \\
4,./start_qemu.sh clear-34500-kvm.img \\
5,改好 ssh, X11forwarding.
# systemctl edit sshd.socket
[Socket]
ListenStream=
ListenStream=22
# systemctl daemon-reload
# systemctl restart sshd.socket
# vi /etc/ssh/sshd_config
PermitRootLogin yes
AllowTcpForwarding yes
X11UseLocalhost yes
X11DisplayOffset 10
X11Forwarding yes
subsystem sftp /usr/libexec/sftp-server
在 host 可以看到 qemu 的 clearOS 的 sshd listen on 10022:
05-11 21:07 [root@kiosk430 ~]# netstat -anlpt |grep qemu
tcp 0 0 0.0.0.0:10022 0.0.0.0:* LISTEN 458036/qemu-system-
tcp 0 0 0.0.0.0:12375 0.0.0.0:* LISTEN 458036/qemu-system-
在 start-qemu.sh 中定義了 port 轉接:
-netdev user,id=mynet0,hostfwd=tcp::${VMN}0022-:22,hostfwd=tcp::${VMN}2375-:2375 \
在 host 可以用 10022 連接 kvm 的 :22
[feuer@kiosk430 ClearOS]$ ssh -p 10022 root@127.0.0.1
在 vm 中使用 "poweroff" 將系統關機。\\

====== 圖形界面 ======
修改 start_qemu.sh
qemu-system-x86_64 \
-enable-kvm \
{UEFI_BIOS} \
-smp sockets=1,cpus=4,cores=2 -cpu host \
-m 4096 \
-vga qxl \
-nographic \
-spice port=5924,disable-ticketing \
-usb \
-device usb-tablet,bus=usb-bus.0 \
-drive file="$IMAGE",if=virtio,aio=threads,format=raw \
-netdev user,id=mynet0,hostfwd=tcp::${VMN}0022-:22,hostfwd=tcp::${VMN}2375-:2375 \
-device virtio-net-pci,netdev=mynet0 \
-debugcon file:debug.log -global isa-debugcon.iobase=0x402 $@
重新下載開機檔案:
rm -v OVMF*.fd
curl -O https://cdn.download.clearlinux.org/image/OVMF.fd
curl -O https://cdn.download.clearlinux.org/image/OVMF_CODE.fd
curl -O https://cdn.download.clearlinux.org/image/OVMF_VARS.fd
擴充 vm 硬碟空間:
[feuer@kiosk430 ClearOS]$ qemu-img resize -f raw clear-34500-kvm.img +10G
Image resized.
啟動 vm:
./start_qemu_spice.sh clear-34500-kvm.img
在 host 執行 "ip a" 可以看到 vm 的 ip:
6: virbr0: mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether 52:54:00:25:d0:b7 brd ff:ff:ff:ff:ff:ff
inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
valid_lft forever preferred_lft forever
執行 remote-viewer spice 來進入 vm :
[feuer@kiosk430 ClearOS]$ remote-viewer spice://192.168.122.1:5924
===== Resize the last partition of the virtual disk =====
登入,在 vm 中執行:"swupd bundle-add storage-utils"
{{:2021-05-11_22-20-55_的螢幕擷圖.png?direct&400|}}
{{:2021-05-11_22-31-12_的螢幕擷圖.png?direct&400|}}
{{:2021-05-11_22-33-53_的螢幕擷圖.png?direct&400|}}
===== Install GDM =====
執行 "swupd bundle-add desktop-autostart"
{{:2021-05-11_22-47-45_的螢幕擷圖.png?direct&400|}}
在 vm 中執行 "reboot" ,就會開啟 gdm 登入。
