一、创建新的虚拟机,启动后错误如下

swtpm_setup: Not overwriting existing state file.
kvm: warning: host doesn't support requested feature: CPUID.07H:EBX.hle [bit 4]
kvm: warning: host doesn't support requested feature: CPUID.07H:EBX.rtm [bit 11]
kvm: Host doesn't support requested features
stopping swtpm instance (pid 2585) due to QEMU startup error
TASK ERROR: start failed: QEMU exited with code 1

通过以上的错误可以看出,是CPU的问题,所以只需要在虚拟机硬件下找到处理器配置,尝试更改类别即可,比如我的将Haswall改为host就可以了。

二、PVE(Proxmox)提示 kvm: -device ide-hd,bus=ide.0,unit=1,drive=drive-ide1,id=ide1,bootindex=101: Can't create IDE unit 1, bus supports only 1 units TASK ERROR: start failed: QEMU exited with code 1错误的解决方案

PVE(Proxmox)在创建虚拟机启动后提示如下错误

kvm: -device ide-hd,bus=ide.0,unit=1,drive=drive-ide1,id=ide1,bootindex=101: Can't create IDE unit 1, bus supports only 1 units
TASK ERROR: start failed: QEMU exited with code 1

问题说明

如果您使用“q35”作为机器类型，则只有 ide0 和 ide2 可用...这是 qemu 的限制

解决方式

转到虚拟机的“硬件”选项下,把硬盘设备中的ide1去掉,重新添加为ide2,或者将ide1修改为ide2即可
