CPU frequency in virsh capabilites differs from lscpu

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? Regards, Mevludin
