Bug Description

The psock_tpacket in the net test from ubuntu_kernel_selftests failed with B-KVM
$ sudo ./psock_tpacket
test: TPACKET_V1 with PACKET_RX_RING open: No such file or directory

Look into the code, it seems that this file not found error is caused by the attempt to access /proc/kallsyms in test_kernel_bit_width():

static int test_kernel_bit_width(void)
{
 char in[512], *ptr;
 int num = 0, fd;
 ssize_t ret;

 fd = open("/proc/kallsyms", O_RDONLY);
 if (fd == -1) {
  perror("open");
  exit(1);
 }

After discussed with Kamal, we're not going to enable this for the KVM kernel.

This test should be skipped if KALLSYMS was not enabled.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
