Proxmox nested on vmware, cannot start vm

[winproof]

hello

i have a problem that i cannot resolv.

i have a win 7 host, with vmware workstation 14, and proxmox inside.

using for test cluster (3 proxmox), all is fine.

but i want create a simple vm (debian 9) for HA test.

i have VT-x/EPT ticked in vmware, and nested options activated on proxmox.

i can create vm (with cpu set to "host") but cannot start, error :

kvm: error: failed to set MSR 0x38d to 0x0
kvm: /home/builder/source/qemu.tmp/target/i386/kvm.c:1833: kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.

with cpu set to "kvm64", vm start, but "stop" on BIOS, or very very very slow, after 10mn there is still cpu activity but nothing more.

a little help please

(sorry for my english, i'm french)

ok, vm is not slow but freezed, one hour after start nothing change, stuck on bios.

I have this same problem. I'm trying to learn Proxmox and compare that to ESXi, but I'm not able to get a VM to start in Proxmox using kvm. There are no errors indicating that the hardware is missing, but VM's never progress past the BIOS screen. When I change the virtualization to software the VM's run, but they're very slow.

What's confusing is that there are no errors. I'm passing the hardware virtualization to Proxmox, and according to Proxmox it see's the hardware virtualization, but no VM's will run using the kvm engine.

This is my first try using Proxmox, I'm trying to learn it and see what it can do.

Including the workaround.
