+Connection error when use PXE+NFS to boot guest
+
+I use NFS+PXE to boot RHEL 5. The installation is slow, and I send Ctrl+Alt+F4, then find that half (but not all) of connections are dropped:

+============================================================================
+I try to use NFS under different situations to test.
+Test 1) Try normal NFS mount. This test successes.
+Test 2) Try to boot a diskless machine via PXE, use a NFS mount point at root. This test suffers the same problem
+
+At test 1)
+NFS client mount an export of the NFS server, and use command "find ." to see if it runs smoothly.
+Result: it runs smoothly for thousands of lines.
+
+Guest machine 3 (NFS server)
+Kernel: 2.6.18-164.el5
+Set up command: virt-install --connect qemu:///system -n dm1 --vnc --accelerate --ram=256 --noreboot --os-type=linux --pxe --os-variant=rhel5 --mac=52:54:00:d1:00:00 --file=/dev/VolGroup00/dm1
+
+NFS client is Guest machine 1 mentioned before.
+
+At test 2)
+Set up a PXE server, write a customized initrd, in which init script uses "mkrootdev -t nfs -o nolock,ro" to set root directory on a NFS mount.
+
+Result: the client machine can boot, but very slowly, with numerous
