Proxmox VE 虚拟机配置xterm.js

1.关闭 VM，并且新增 serial port 給 VM 在PVE Host 中用 qm 命令建立 serial port，假設我的 VM ID 是 100

qm set 100 -serial0 socket

2.重新开启 VM，用 dmesg 验证是否有 ttyS 出现

dmesg | grep ttyS

如果出現如下代表有了

[    3.521757] 00:04: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A

3.接下来配置VM的grub，进入VM的ssh

cd /etc/default/
vim grub

修改grub中的GRUB_CMDLINE_LINUX值

GRUB_CMDLINE_LINUX="quiet console=tty0 console=ttyS0,115200”

4.更新grub

# debian based
update-grub

# redhat based
grub2-mkconfig --output=/boot/grub2/grub.cfg

5.在虚拟机添加

/etc/init.d/ttyS0.conf

并添加如下

# ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.
start on stopped rc RUNLEVEL=[12345]
stop on runlevel [!12345]
respawn
exec /sbin/getty -L 115200 ttyS0 vt102

6.设置自启动

systemctl enable serial-getty@ttyS0.service
systemctl start serial-getty@ttyS0.service

重启VM，测试xterm，已经可以用
