Is it a production server?
can you append the following in the kernel parameters and check (only if it's a non-production server. Don't blame me if things go wrong! )
Also, if possible, please post dmesg output. What I have seen so far if the VMs are created through a template or cloned or P2V-ed, things go wrong and kernel some times fails to detect hard disk or fails to mount properly.

Hello,
I was wondering if it would be possible to run two VMs one with services for IPv4 and the other one with services for IPv6. The main physical system would be connected to a IPv6 switch.
I think it should be fine but I would like to hear out your comments. (1 Reply)

mnt
MNT(3) Library Functions Manual MNT(3)NAME
mnt - attach to 9P servers
SYNOPSIS
#M
DESCRIPTION
The mount driver is used by the mount system call (but not bind; see bind(2)) to connect the name space of a process to the service pro-
vided by a 9P server over a communications channel. After the mount, system calls involving files in that portion of the name space will
be converted by the mount driver into the appropriate 9P messages to the server.
The mount system call issues session and attach(5) messages to the server to identify and validate the user of the connection. Each dis-
tinct user of a connection must mount it separately; the mount driver multiplexes the access of the various users and their processes to
the service.
File-oriented system calls are converted by the kernel into messages in the 9P protocol. Within the kernel, 9P is implemented by procedure
calls to the various kernel device drivers. The mount driver translates these procedure calls into remote procedure calls to be transmit-
ted as messages over the communication channel to the server. Each message is implemented by a write of the corresponding protocol message
to the server channel followed by a read on the server channel to get the reply. Errors in the reply message are turned into system call
error returns.
A read(2) or write system call on a file served by the mount driver may be translated into more than one message, since there is a maximum
data size for a 9P message. The system call will return when the specified number of bytes have been transferred or a short reply is
returned.
The string is an illegal file name, so this device can only be accessed directly by the kernel.
SEE ALSO bind(2)SOURCE
/sys/src/9/port/devmnt.c
BUGS
When mounting a service through the mount driver, that is, when the channel being multiplexed is itself a file being served by the mount
driver, large messages may be broken in two.
