nemu+hugepages breaks kata network #1698
Description
Description of problem
While trying to run kata using virtio-fs, I enabled hugepages on the config file, but when running the docker integration tests, found that the package manager tests failed.
Tried to reproduce the issue manually and it seems that network is broken:
$ grep ^enable_huge /usr/share/defaults/kata-containers/configuration.toml
enable_hugepages = true

W: Some index files failed to download. They have been ignored, or old ones used instead.
tried also getting some files using wget or curl and got timeouts.
This is not only related with virtio-fs as I could also reproduce it using 9p with hugepages enabled.
I don't see any related failure in the logs that can give us a hint of what might be wrong.
I also tried using the default qemu-lite and hugepages enabled, the network works correctly.
So it seems a problem with nemu and hugepages.
