Bug Description

Running 16.04 server without X under latest Oracle Virtual Box 5.0.12 on Windows. After issuing 'shutdown -r now' the following boot process is not successful and hangs with message:
---[ end of Kernel panic - not syncing: VFS: unable to mound root fs on unknown-block(0,0)

If using 'shutdown -h now' and then staring the machine anew from Virtual Box manager, then the system starts as it should. Thus, for short, warm reboot hangs and cold reboot operates as desired. I have the feeling that this behavior was introduced with kernel 4.3, but I cannot swear on it.

WORKAROUND: Switch network adapter type to Intel Pro/1000 MT Desktop from paravirtualized network (virtio-net).

Christian Bachmaier, thank you for reporting this and helping make Ubuntu better.

At your earliest convenience, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

So I tried kernels 4.2.8, 4.1.0 and 3.13.11.11 . All show the same beaviour: kernel panic after warm reboot. However now I played with the setting of Virtual Box and switched back the network adapter type paravirtualized network (virtio-net) from to Virtual Box's default Intel Pro/1000 MT Desktop OEM). As far I can remember this was probably before the update to kernel 4.3 from 4.2. Thus the latter has to say nothing. As the network performance seems to be roughly the same, this solves the bug for me, or is at least a reasonable workaround for a productive machine.

Thus all looks like it is really a bug in Virtual Box as I have indicated in my first posting?

Thanx for your great help! Should I or can I close this bug then, or switch it to the Virtual Box Team, or Christopher, could you do this?

Now I am confused, I already have tested 3.13.x with 3.13.11.11 and on shutdown -r now it hangs with kernel panic when using virtio-net of Oracle Virtual Box instead the HW Emulation of the Intel card. See my previous post. Same with the newest kernel.

Hello!

I was unable to reproduce 'shutdown -r' hangs with kernel panic with similar setup like described here (VBox 5.0.12, virtio-net, Ubuntu 16.04 latest nightly build). Would be good to get more information about host/guest config or even better way is attach/share somewhere guest appliance in OVA format (File->Export Appliance)
Thanks!

Hi,

as I wrote in my first comment, my host is a M$ Windows system, on which I prepare the vms to run later on a dedicated Solaris virtualization server. My first thought was it is a kernel problem. However, kernel panic still is reproducible with todays version of 16.04 as guest (all updates included) and VirtualBox 5.0.14 r105127 when using virtio-net and warm boot. My network config is in bridge mode to the physical adapter of the Windows host. Chipset emulation PIIX3, IO-APIC active, no audio, VT-x/AMD-V on, Nested Paging, KVM-paravitualization on, template Ubuntu (64-bit), SATA controller in AHCI mode, hard disk as vmdk file.

I assume your host is Linux... maybe that's the key. Then Ubuntu seems to have no problem, neither as guest nor as host. At least good to know.

Sorry that I cannot provide an ova: This is a copy of my production system with the new LTS version for testing purposes containing a lot of sensible data. But basically the guest is a 16.04 standard server installation without X.

Hope that helps at least a bit.

Hi Chris,

I tested this issue on Windows 7, 10 and Ubuntu 15.10 hosts, NAT and bridge networking using virtio-net adapter.
I think guest configuration is also important. Do you have any CIFS/NFS/etc shares mounted in the guest? Sounds like 'Unable to mount/umount root fs' and networking could be the key.

Hi Alex,

my backup folder to a zfs filesystem is mounted via NFS automount. Here is my config:

$ cd /etc/auto.master.d/
$ cat backup.auto
hanuta -fstype=nfs,rw,sloppy backupserver.mycompany.de:/vmdata/extern/hanuta
$ cat backup.autofs
/backup /etc/auto.master.d/backup.auto
$

However, I have no script or similiar which changes into the directory /backup/hanua during boot. So it will not be mounted and thus is probably not causal. Another thing is that backupserver is not reachable from my windows box, but only from the production server due to security restrictions.

Thanks,

Chris

Hi, I found a similar problem with a Debian Jessie VM with kernel 3.16.0-4-686-pae, so the situation may not be completely applicable to Ubuntu 16.04, but I think it may help.

I found that unloading just the virtio_net module before rebooting made the kernel panic not happen (no need to change NIC driver to Intel).

So as a temporary workaround, if your VM network interface is eth0, you may make its entry in /etc/newtwork/interfaces look like this:

    iface eth0 inet dhcp
        pre-up modprobe virtio_net
        post-down modprobe -r virtio_net

This worked for me and can be done completely inside of the VM.

I hope that this issue gets fixed since it may be a showstopper for remotely managed VMs. Thanks!
