Problem Update Proxmox 3.1 to 4.2

[claudiomiguelmuller]

Hi,
i had proxmox 3.1 with 2 Vms:
- VM 100 Centos with telnet and samba
- VM 102 Linux Old with postfix

I format new HD with Proxmox 4.2 and restore this 2 Vms.

I install proxmox 4.2 with basic configurations, no firewall in VMs.
Firewall in proxmox basic.

After new proxmox instaled,
the VM 100 drop telnet and samba.
does not have a certain time, we found what it is,
We do not change any settings in this vm.

and this began to occur after the new installation of Proxmox 4.2

- VM 102 OK in new proxmox 4.2


what could it be? where can I see it? by logs VM100 Centos have not found anything different

Could be a thousand things or nothing:

• Is this a KVM or a OpenVZ VM you migrated?
• Please post host and guest network configuration
• What is Linux old?
• What is 'Firewall in proxmox basic'?

I'll try to explain what I know, because I'm not expert in Proxmox. I am sorry for my english.

> Is this a KVM or the OpenVZ VM you migrated?

I had a Proxmox 3.1 with 2 vms.
I did backup for two vms.

I installed a new hard drive and formatted it with the Proxmox 4.2,
I restored the two vms.

> Please post host and guest network configuration
What kind of information would be?

> What is Linux old?
Sorry, I restored two vms, one is an old postfix that worked well, just another given problem (Centos problem).

> What is 'Firewall in Proxmox basic'?
I have not changed the installation of Proxmox, then the firewall is the default installation of both the server and the vm.

Sorry, this information does not help :-(

interesting

Proxmox in version 3.1, 3.3, 4.0 functions normally
Proxmox in version 4.2 is having trouble cutting samba and telnet

I have a server just for testing

Hello,
in my case it seems that decided.

In the VMs that are in Proxmox 4.2 changed all network cards for E1000 and everything seems fine.

In the VMs that are in Proxmox 3.1 / 3.3 the same VMs work with Virtio network card, but the virtio does not work well in Proxmox 4.2
