Hello All! I had installed new version of Proxmox on raid1. Core i7 4770+32 GB Ram.
And i have issues with high latency ping to VM. (about 1000ms). VM Windows Server 2016 - With all updates.
Im using stable virtio drivers and virtio paravirtualized network.
If I ping Proxmox host node ping ok (1 ms). Linux bridge is used for network connect. Without firewall or something. All hardware issues with network excluded.
May be its problem with kernel patches Melthdown, spectr, pti?

Similar config on PVE 4 with old kernel having no problems.
 
Is Proxmox VE up-to-date? I am asking, as we recently released Proxmox VE 6.1.
