Timeout of network interface with OpenBSD 4.5 VM

Timeout of network interface with OpenBSD 4.5 VM

Hi all!

Until today I was using OpenBSD 4.5 like KVM virtual machine on Ubuntu
Hardy Heron server amd64 with KVM-62. But due to a bug that could affect
to hosts with a high rate of I/O [1], I decided to update to KVM-88
compiled from sources from KVM site.

Although with the other virtual machines that it had in the host I did
not have problems, I have now some problems with the installation of
OpenBSD on KVM-88

Next I paste the output when connecting to the VM by means of serial
console from the host machine. After 'mtrr: Pentium Pro MTRR support', I
see an 'u' followed sometimes by an 'k', and the operating system is
rebooted repetitively when arriving at this instance.

If I start the VM with the --no-acpi option, OpenBSD boots without
problems, but I obtain timeouts of the network interface and this host
loses the connectivity with the rest of the network maintaining the
option model=ne2k_pci (same configuration used for KVM-62) when start
the VM. Some idea of which can be the problem?

Thanks in advance.

Regards,
Daniel

And he goes on to post a minimal kernel config that achieves that goal.

I was trying with the configuration suggested by Nick, but in this case
I get a panic [1]. Reading a post of Dmitiry Zotikov [2], it would seem
that the one is a problem with Qemu.

Thanks for your reply.

Well, I was recently able to get 32 bit OpenBSD 4.5 running under
kvm-88 by taking the stock GENERIC config and only disabling the mpbios
device.

I'll try to drop the kernel and the config file somewhere
later this morning to see if it's just a fluke for
KVM-88 on 2.6.27 on a core2duo.

The OpenBSD virtual machines have 256M allocated, e1000 NIC, and vde backing
it.

Firstly, thank you very much by to take the trouble to test and to put
the files in a site.

I was testing the compiled kernels that you provided to me in the VM
with OpenBSD 4.5 in my host with KVM-88 running Ubuntu Hardy Heron
server amd64 on a Athlon 64 X2 3800+ using a kernel 2.6.24-19-server.

The boot parameters were the following:

# OpenBSD
$KVM -hda /dev/vm/fugu-disk -m 512 -boot c -net \
 nic,vlan=0,macaddr=00:16:3e:00:00:35,model=ne2k_pci -net tap \
 -daemonize -vnc :4 -k es -localtime -serial \
 telnet:localhost:4001,server,nowait

bsd.kvm3 and bsd.kvm4 boots without problems and the VM has connectivity
with the rest of my LAN, nevertheless bsd.kvm3l boots without problems
but the network interface does not take the static IP assigned (in none
of the three cases it uses DHCP).

With kernel bsd.kvm3l:

fugu:~# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33204
        priority: 0
        groups: lo
        inet 127.0.0.1 netmask 0xff000000
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2
enc0: flags=0<> mtu 1536
        priority: 0

With kernel bsd.kvm[34]:

fugu:~# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33204
        priority: 0
        groups: lo
        inet 127.0.0.1 netmask 0xff000000
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
ne3: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        lladdr 00:16:3e:00:00:35
        priority: 0
        groups: egress
        media: Ethernet 10baseT full-duplex
        inet 10.1.0.12 netmask 0xffffff00 broadcast 10.1.0.255
        inet6 fe80::216:3eff:fe00:35%ne3 prefixlen 64 scopeid 0x1
enc0: flags=0<> mtu 1536
        priority: 0

On the other hand, also I tried to compile the kernel with the
configuration files that you provided to me booting the operating system
with a kernel GENERIC and the option --no-acpi of kvm so that boot
finishes successful (although this way did not have connectivity),
although under these circumstances some of the locally compiled kernels
did not work.

KVM4 boots without problems, but giving a 'ne3: device timeout' and the
VM loses connectivity with the LAN even though the network interface is
configured with its static IP. KVM3 boots OK and it doesn't presents
networking problems. KVM3L boots OK but the interface is not configured
with its static IP as in the previous case with the kernel compiled for
you.

Also I was trying to boot the VM with the KVM option model=e1000. In
this case, the kernels locally compiled with KVM3 and KVM3L didn't
present problems when boot or with the configuration of network,
nevertheless, with kernel locally compiled with KVM4L were rebooted
after mttr similar to as it happened with GENERIC kernel:

and occasionally the boot finishes with:

With the three compiled kernels that you provided to me, I didn't have
no kind of problem during boot or of networking using model=e1000,
although it draws attention to me to observe these differences that
commented to you. This difference will be related to hardware that I am
using?

CPU: Athlon 64 X2 3800+
Motherboard: M2N32 SLI
Network interface: 2 x nVidia MCP55

I don't have much experience compiling OpenBSD kernel, but the procedure
that I used was the following one:

* Download ftp://ftp.openbsd.org/pub/OpenBSD/4.5/sys.tar.gz
* Copy it to /usr/src
* To extract the files in the tarball.
* Copy the config file to /usr/src/sys/arch/i386/conf/
* run 'config <KVM_KERNEL_CONFG>'
* cd /usr/src/sys/arch/i386/compile/<KVM_KERNEL_CONFG>
* run 'make depend' and 'make'.


Thanks again for your time.

Regards,
Daniel
