Triaging old bug tickets ... can you still reproduce this issue with the

Title:
Connection error when use PXE+NFS to boot guest
Status in QEMU:
Incomplete
Bug description:
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:
nfs: server 192.168.122.50 OK
nfs: server 192.168.122.50 OK

I have checked that there is no IP conflict.
Host machine
Kernel: 2.6.32.9-70.fc12.x86_64
QEMU version: 0.12.3-2.fc12.x86_64
libvirt version: 0.7.1-15.fc12.x86_64
Guest machine 1 (NFS server)
Kernel: 2.6.18-164.el5
nfs-utils version: 1.0.9-42.el5
Set up command: virt-install --connect qemu:///system -n m5 --vnc
--accelerate --ram=256 --noreboot --os-type=linux --pxe --os-variant=rhel5
--mac=52:54:00:50:00:00 --file=/dev/VolGroup00/m5
Guest machine 2 (the machine to be installed via PXE+NFS)
Set up command: virt-install --connect qemu:///system -n e51 --vnc
--accelerate --ram=128 --noreboot --os-type=linux --pxe –os-variant=rhel5
--mac=52:54:00:51:01:00 --file=/dev/VolGroup00/e51
============================================================================
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
nfs: server 192.168.122.110 OK
nfs: server 192.168.122.110 not responding, still trying
NFS server: it is Guest machine 3
Client to be booted: Guest machine 4
Set up command: virt-install --connect qemu:///system -n de11 --vnc
--accelerate --ram=128 --noreboot --os-type=linux --pxe –os-variant=rhel5
--nodisk --mac=52:54:00:d1:01:00
