Centos7 guest paused after minutes when kvm is enabled with AMD CPU

Some of my centos7 images guest paused after minutes.
Not all images like this, but I can't find the obvious difference.

I cannot resume the paused VM.

Here was the error:
virsh resume 1
error: Failed to resume domain 1
error: internal error: unable to execute QEMU command 'cont': Resetting the Virtual Machine is required

I can suspend and resume the VM with virsh command, but I cannot resume it when the VM paused itself.

The same VM  ran fine when I use "qemu" instead of "kvm".

I cannot find any error in the host and only error info that I could find in the guest is:

Jan 14 22:57:49 localhost kernel: amd64_edac_mod: Unknown symbol amd_unregister_ecc_decoder (err 0)
Jan 14 22:57:49 localhost kernel: amd64_edac_mod: Unknown symbol amd_register_ecc_decoder (err 0)
Jan 14 22:57:49  localhost kernel: amd64_edac_mod: Unknown symbol amd_report_gart_errors (err 0)

It seems to be unimportant information.

1. I tried to use "host-model".  Not work.

My questions:
1. Where can I find more information and how to solve this problem?

Some informations:
