Dear @RodrigoDLopez,
Thank you for taking the initiative to define a useful default value for the
`vm.memballoon.stats.period` variable.
After identifying the configuration tweaks that resolved our previous
issues, I documented them using Ansible to ensure parameters are consistently
set as needed. For example:
```
- name: Agent configuration customization - Stats period.
ansible.builtin.lineinfile:
path: /etc/cloudstack/agent/agent.properties
regexp: '^vm.memballoon.stats.period'
line: 'vm.memballoon.stats.period=5'
state: present
ignore_errors: true
```
I’d also like to suggest a few additional defaults that could be beneficial
to consider:
```
- name: Agent configuration customization - CPU mode.
ansible.builtin.lineinfile:
path: /etc/cloudstack/agent/agent.properties
regexp: '^guest.cpu.mode'
line: 'guest.cpu.mode=host-passthrough'
state: present
ignore_errors: true
- name: Agent configuration customization - CPU features.
ansible.builtin.lineinfile:
path: /etc/cloudstack/agent/agent.properties
regexp: '^guest.cpu.features'
line: 'guest.cpu.features=vmx aes smx mmx ht'
state: present
ignore_errors: true
- name: Agent configuration customization - Video driver.
ansible.builtin.lineinfile:
path: /etc/cloudstack/agent/agent.properties
regexp: '^vm.video.hardware'
line: 'vm.video.hardware=qxl'
state: present
ignore_errors: true
- name: Agent configuration customization - Console proxy.
ansible.builtin.lineinfile:
path: /etc/cloudstack/agent/agent.properties
regexp: '^consoleproxy.httpListenPort'
line: 'consoleproxy.httpListenPort=443'
state: present
ignore_errors: true
- name: Configuring EUFI booting.
ansible.builtin.copy:
dest: /etc/cloudstack/agent/uefi.properties
content: |
guest.nvram.template.secure=/usr/share/OVMF/OVMF_VARS_4M.ms.fd
guest.nvram.template.legacy=/usr/share/OVMF/OVMF_VARS_4M.fd
guest.nvram.path=/var/lib/libvirt/qemu/nvram/
guest.loader.secure=/usr/share/OVMF/OVMF_CODE_4M.secboot.fd
guest.loader.legacy=/usr/share/OVMF/OVMF_CODE_4M.fd
```
Lastly, it might also be worth setting the log level to DEBUG by default,
since detailed logs are **always** required for support and troubleshooting:
```
- name: Agent configuration customization - Debug level logging.
ansible.builtin.replace:
path: /etc/cloudstack/agent/log4j-cloud.xml
regexp: 'INFO'
replace: 'DEBUG'
backup: yes
ignore_errors: true
```
These are just suggestions, shared to contribute to the collective knowledge
of developers and practitioners.
Best regards,
