SpiralLinux/Debian guest cannot access internet from KVM

[manujchandra]

Hi,

When I run SpiralLinux 12 as a guest from a SpiralLinux 12 as a host, using QEMU/KVM/Virtual machine Manager, either live or install, the guest cannot access the internet. I am using NAT.

It seems it's connected to eth0 but it cannot access the internet. I searched on the net but could not find a solution. I also tried Debian Live XFCE 12.5 but it too cannot access the internet.

Internet is working fine on the Host. I am using Portmaster and ufw on the host. Don't know if they are the problem. I checked Portmaster's blocked list, but it does not show anything pertaining to the issue.

Has anyone experienced something similar?

Another issue is that if I install VirtualBox, the installation completes, but I cannot access/open VirtualBox. There is no application or command.

Thanks.

I managed to install Virtualbox from the .deb provided by their website, and the guest can access internet from VirtualBox. So it's a KVM issue.
