pirateghost: >> Did you turn a firewall on during the setup of the KVM? thx, the Proxmox host server is built from iso, i did not changed anything via SSH, i did not found "Firewall" tab in proxmox. >> Did you assign the vmbr0 to your KVM or did you select NAT? Yes, in VM configuration is vmbr0 and model is VirtIO For my other VM (Centos 5.11) i used NAT. I tried several configurations, nothing worked, so i set to vmbr0 & reboot VM, but still no luck. I think if Gateway IP is needed, i might be entering wrong GW IP in /etc/sysconfig/network-scripts/ifcfg-eth0 (on VM), i asked my server provider, but i got no GW IP from them (i have only one IP assigned (/32). host server GW IP is known, but not sure if that is what i need to set in VM
