⚠️ Potential issue

Fix table formatting for proper Markdown rendering.

The Series table provides valuable information, but its formatting needs adjustment for correct Markdown rendering. Please apply the following changes:

  1. Add a leading pipe (|) to each row.
  2. Ensure all rows have the same number of columns (6 in total).
  3. Add a separator row after the header row.

Here's the corrected table format:

|                            |  U  |  O  |  CX  |  M  |  RT  |
|----------------------------|-----|-----|------|-----|------|

| *Overcommitted Memory*     |     |  ✓  |      |     |      |
| *Dedicated CPU*            |     |     |  ✓   |     |  ✓   |
| *Burstable CPU performance*|  ✓  |  ✓  |      |  ✓  |      |
| *Isolated emulator threads*|     |     |  ✓   |     |  ✓   |
| *vNUMA*                    |     |     |  ✓   |     |  ✓   |
| *vCPU-To-Memory Ratio*     | 1:4 | 1:4 |  1:2 | 1:8 | 1:4  |

This will ensure the table is correctly displayed in Markdown viewers.

## U Series

The U Series is quite neutral and provides resources for
general purpose applications.

*U* is the abbreviation for "Universal", hinting at the universal
attitude towards workloads.

VMs of instance types will share physical CPU cores on a
time-slice basis with other VMs.

### U Series Characteristics

Specific characteristics of this series are:
- *Burstable CPU performance* - The workload has a baseline compute
performance but is permitted to burst beyond this baseline, if
excess compute resources are available.
- *vCPU-To-Memory Ratio (1:4)* - A vCPU-to-Memory ratio of 1:4, for less
noise per node.

## O Series

The O Series is based on the U Series, with the only difference
being that memory is overcommitted.

*O* is the abbreviation for "Overcommitted".

### UO Series Characteristics

Specific characteristics of this series are:
- *Burstable CPU performance* - The workload has a baseline compute
performance but is permitted to burst beyond this baseline, if
excess compute resources are available.
- *Overcommitted Memory* - Memory is over-committed in order to achieve
a higher workload density.
- *vCPU-To-Memory Ratio (1:4)* - A vCPU-to-Memory ratio of 1:4, for less
noise per node.

## CX Series

The CX Series provides exclusive compute resources for compute
intensive applications.

*CX* is the abbreviation of "Compute Exclusive".

The exclusive resources are given to the compute threads of the
VM. In order to ensure this, some additional cores (depending
on the number of disks and NICs) will be requested to offload
the IO threading from cores dedicated to the workload.
In addition, in this series, the NUMA topology of the used
cores is provided to the VM.

### CX Series Characteristics

Specific characteristics of this series are:
- *Hugepages* - Hugepages are used in order to improve memory
performance.
- *Dedicated CPU* - Physical cores are exclusively assigned to every
vCPU in order to provide fixed and high compute guarantees to the
workload.
- *Isolated emulator threads* - Hypervisor emulator threads are isolated
from the vCPUs in order to reduce emaulation related impact on the
workload.
- *vNUMA* - Physical NUMA topology is reflected in the guest in order to
optimize guest sided cache utilization.
- *vCPU-To-Memory Ratio (1:2)* - A vCPU-to-Memory ratio of 1:2.

## M Series

The M Series provides resources for memory intensive
applications.

*M* is the abbreviation of "Memory".

### M Series Characteristics

Specific characteristics of this series are:
- *Hugepages* - Hugepages are used in order to improve memory
performance.
- *Burstable CPU performance* - The workload has a baseline compute
performance but is permitted to burst beyond this baseline, if
excess compute resources are available.
- *vCPU-To-Memory Ratio (1:8)* - A vCPU-to-Memory ratio of 1:8, for much
less noise per node.

## RT Series

The RT Series provides resources for realtime applications, like Oslat.

*RT* is the abbreviation for "realtime".

This series of instance types requires nodes capable of running
realtime applications.

### RT Series Characteristics

Specific characteristics of this series are:
- *Hugepages* - Hugepages are used in order to improve memory
performance.
- *Dedicated CPU* - Physical cores are exclusively assigned to every
vCPU in order to provide fixed and high compute guarantees to the
workload.
- *Isolated emulator threads* - Hypervisor emulator threads are isolated
from the vCPUs in order to reduce emaulation related impact on the
workload.
- *vCPU-To-Memory Ratio (1:4)* - A vCPU-to-Memory ratio of 1:4 starting from
the medium size.

🛠️ Refactor suggestion

Recommend specifying commit hashes for 'vm-disk' and 'vm-instance'

Currently, both vm-disk 0.1.0 and vm-instance 0.1.0 are using HEAD. To maintain build stability and prevent unintended changes from affecting the builds, it's advisable to pin these versions to specific commit hashes.
