Solve the VPN dialing 619 error in KVM virtual WINXP in DEBIAN7.0

DEBIAN7.0 solves the VPN dialing 619 error in KVM virtual WINXP. dear friends, I finally switched to DEBIAN7.0. Then, use KVM to directly start the earlier WINXP image. In the Internet connection mode, the bridge mode is changed to the NAT to ETH0 mode. as a result, the error 619 is always reported when the original VPN is redeployed. Solution: Solve the VPN dialing 619 error in KVM virtual WINXP under DEBIAN7.0. you finally changed to DEBIAN7.0. Then, use KVM to directly start the earlier WINXP image. In the Internet connection mode, the bridge mode is changed to the NAT to ETH0 mode. as a result, the error 619 is always reported when the original VPN is redeployed. Solution: directly run the following module load command on the DEBIAN7.0 host machine: # modprobe ip_nat_pptp # modprobe ip_conntrack_pptp re-dial the VPN in the WINXP virtual machine. Everything is back to normal !! To avoid manual start, you can directly vi/etc/modules the following content: loop ip_net_pptp ip_conntrack_pptp ip_nat_proto_gre ip_conntrack_proto_gre so that relevant modules can be automatically loaded after each system start. If a common user uses virt-manager to connect to a virtual machine, you will receive an error indicating that the user cannot be connected. you need to use the usermod-g libvirt user command to add the user to the libvirt group. In this way, the user can use virt-manager to use the client host for VPN dialing !! There is also a problem with the client host accessing the local lan ftp server. Run the command: # modprobe ip_conntrack_ftp # modprobe ip_nat_ftp to restore normal access
