Functionnal VM won't boot anymore (stuck on autoboot)

[mathgoy]

Hi all,

 

I have Home Assistant running on a VM for 18months and today, as I rebooted it, it won't start again.

 

Here is what I will show when booting:

 

It will stay like that forever and load the CPU to 100%.

 

The log is the following:

Any idea?

 

Thanks

It seems the vm didn't shutdown properly/gracefully.

One user is reporting the following steps to work:

1. At the “Autoboot” screen, draw focus to your vm and press the number “2” on the keyboard

 

2. When the next screen is displayed, press the “Enter/Return” key:

 

3. Once this next screen appears, the HA vm will start normally:

 

From there, by shutting down and/or restarting the HA vm properly/gracefully, the vm should boot again without any issues from then on out.

Hi,

Thanks for your feedback.

I found out that topic as well.

However, it doesnt work.

Keep looping (just like the video posted by one of the users)

[ghost82]

Check if your vdisk is full with command:

qemu-img info /path/to/vdisk.img

 

[mathgoy]

Looks like I might run out of space:

image: /mnt/user/domains/Hassos/hassos_ova-5.13.qcow2
file format: qcow2
virtual size: 32 GiB (34359738368 bytes)
disk size: 31.4 GiB
cluster_size: 65536
Format specific information:
    compat: 1.1
    compression type: zlib
    lazy refcounts: false
    refcount bits: 16
    corrupt: false

 

 

How can I increase the size?

[ghost82]

With qemu-img:

qemu-img resize /mnt/user/domains/Hassos/hassos_ova-5.13.qcow2 +10G

this will increase the disk size from 32 to 42 Gb (+10).

However, the +10Gb space will be unallocated.

So you need to mount this virtual disk and resize the partition to use this unallocated space.

You can create a new virtual machine which boots a gparted live iso with the hassos_ova-5.13.qcow2 disk attached to it.

I recommend creating a permanent "utility" VM with all the toys and tools installed on its vdisk, then temporarily attach the vdisks you need to operate on as secondary disks. Much easier to manage boot order, and almost no chance of accidentally booting the target vdisk with the wrong XML by mistake. Plus, you can install quite the array of solutions, you aren't locked into just gparted.

Hi, thanks for the feedback

 

I increased the size the way you proposed it @ghost82 and it worked right away (using the one single command)

Didn't have to reallocate the 10GB I added.

No idea why.
