KVM problems after power failure

After an unplanned shutdown, a Windows Server 2012 KVM on my Antsle One Ultra would not start (Internal error: Did not find USB device). I created a new VM that does boot up, but there are still a couple of problems:

  1. fsck reports "dirty bit is set" which comes back every time I reboot. I'm not sure how much of a problem this is.

[email protected]:~ # fsck -ARV -a -w
fsck from util-linux 2.28.2
Checking all file systems.
[/usr/sbin/fsck.vfat (1) -- /boot] fsck.vfat -a -w /dev/sda2
fsck.fat 4.0 (2016-05-06)
0x41: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
Automatically removing dirty bit.
Performing changes.
/dev/sda2: 353 files, 71464/258078 clusters

2.  RDP does not seem to work any more. I cannot RDP to like I used to, even on the VMs that were unaffected.

Any suggestions?

login to your antsle with root

run the following to make sure the private ip and iptables looks good


iptables -n -L |grep ' '

then run
