How you got this error? after fresh install CentOS 7?

Could you post your Proxmox VE version pveversion -v

EDIT: and VM config as well qm config <VMID>
 
Access to the server is suddenly cut off. I don't know why. sometimes the same problem happens in other vms. I also want to ask something. is the type of ethernet card correct? According to what we choose ethernet cards. e1000 is used here. I don't know if it has anything to do with the problem but I wanted to ask

-Please update your Proxmox VE to the current version
Do you think it is related to this problem . If there is no obligation, I cannot do this immediately because we use it on too many servers.Is there any exact information about the problem?

- Did see if there any error in syslog or journalctl?
how do i check this ?

-Try to use VirtIO as a Network Device
What is the difference between. how can i make this change. Would it be a problem if I did it from gui. will the mac address change when i change it?

first try to use VirtIO as a network device.

What is the difference between.
see here and here to see what the difference is

how can i make this change. Would it be a problem if I did it from gui
Yes through gui go to Datacenter -> NodeName -> VMID -> Hardware -> Network Device click edit and chose [VirtIO]

will the mac address change when i change it?
No.
 
I want to ask something. Are the speeds of the two Ethernet cards the same? 10 GB? And if I change VirtIO, will I do something about the driver in the virtual server. Will it automatically recognize this card? how can i see this. I need to choose which server version or infrastructure. eg windows 10, windows 2008, 2016, centos 7 and centos 8. Which one should I choose when installing a new operating system is there a matrix?

thanks
