CPU frequency in virsh capabilites differs from lscpu

[Mevludin Blazevic <mevludin.blazevic@xxxxxxxxxxxxxx>]

Hi all,

typing virsh capabilities on my one of my server results in the following output:

  <host>
    <uuid>5a692c00-7544-11eb-8000-ac1f6b365280</uuid>
    <cpu>
      <arch>x86_64</arch>
      <model>EPYC-Rome</model>
      <vendor>AMD</vendor>
      <microcode version='137367637'/>
      <counter name='tsc' frequency='2799999000'>

lscpu however shows "CPU max MHz" as 2800.0000 on all servers. On my other machines, virsh capabilites  shows the max frequency as follows:       

<vendor>AMD</vendor>

      <microcode version='137367629'/>
      <counter name='tsc' frequency='2800000000'/>

libvirt and qemu version are btw identical. I assume that the CPU clock speed may differ or is it a libvirt configuration that I need to adjust?
