##### ISSUE TYPE
<!-- Pick one below and delete the rest -->
* Improvement Request
##### COMPONENT NAME
<!--
Categorize the issue, e.g. API, VR, VPN, UI, etc.
-->
~~~
Agent, Core
~~~
##### CLOUDSTACK VERSION
<!--
New line separated list of affected versions, commit ID for issues on main branch.
-->
~~~
4.16.0-Snapshot
~~~
##### CONFIGURATION
<!--
Information about the configuration if relevant, e.g. basic network, advanced networking, etc. N/A otherwise
-->
Built the latest qemu version from source
##### OS / ENVIRONMENT
<!--
Information about the environment if relevant, N/A otherwise
-->
Ubuntu 20.04 and newer
##### SUMMARY
<!-- Explain the problem/feature briefly -->
CS Agent requires `qemu-kvm` installation. However, newer versions of `qemu` have dropped dependency on `qemu-kvm` in favor of `qemu-system-x86`.
If I build and install the latest `qemu` from source, I'm unable to install the CloudStack Agent due to its dependency on `qemu-kvm`, which was dropped in recent releases of `qemu`.
Thus, I can't use the latest release of `qemu`, since trying to `apt install -y qemu-kvm` yields in the following error :
```
bku@ttx0:~/work/qemu/build$ sudo apt install -y qemu-kvm
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'qemu-system-x86' instead of 'qemu-kvm'
qemu-system-x86 is already the newest version (1:5.2+dfsg-9ubuntu3.1).
qemu-system-x86 set to manually installed.
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
cloudstack-agent : Depends: qemu-kvm (>= 2.5)
Depends: ebtables but it is not going to be installed
Depends: vlan but it is not going to be installed
Depends: ipset but it is not going to be installed
Depends: python3-libvirt but it is not going to be installed
Depends: ethtool but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
```
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
1. Clone qemu repository
2. Build and install qemu from master
3. Install a stock libvirt for Ubuntu
3. Validate qemu and virsh installation: `qemu-img --version` , `libvirtd --version`
4. Try to install CloudStack Agent on the node
5. Observe error installing the CS agent
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
Agent works with the latest qemu and libvirt
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
Fail to install CS Agent on the node with the latest `qemu` is installed

@weizhouapache @tetra12 I'm not sure how we can insert this altered dependency but for sure we'll need a separate packaging for newer distributions. If we feel it serves a purpose we should support it, but it will cost us a lot of extra effort to maintain.
Can we use a replace.property to insert the string 'qemu-kvm-x86' in the package?

@rhtyd
it looks he built qemu 5.2 from source, which does not have qemu-kvm package any more.
ps:
official qemu version in ubuntu 20.04 is 4.2, which works fine in cloudstack)
official qemu version n ubuntu 21.04 is 5.2, which does not contain qemu-kvm package. it is not LTS.

@tetra12
`qemu-kvm (>= 2.5) | qemu-system-x86 (>= 5.2)` means it is ok if one of `qemu-kvm (>= 2.5)` and `qemu-system-x86 (>= 5.2)` is installed.

Even if we remove the dependency so cloudstack-agent can be installed, we do not know if it works with the new qemu 5.2, nobody have tested it.
@tetra12 I suggest you to remove your self-build qemu 5.2 and install qemu from official apt repository on ubuntu 20.04, it works fine.

@rhtyd @weizhouapache
I need to customize QEMU and built a master from sources, which is 6.1.0-RC4 now.
`qemu-kvm` package was the wrapper over `qemu-kvm-x86` in older 4.x QEMU, which is shipped with Ubuntu 20.04.
QEMU provides it, not OS. It has been removed starting from 5.x and Ubuntu 21.04, which ships 5.2, also doesn't ship `qemu-kvm`
