nice to know this video helped you sir

yes of course. the OS is Linux then you need only to change the IP address and to be sure it is reachable

When working with devstack, it's important to understand that it is not intended to be a fully functioning openstack installation. It is a tool for developers. As such, the devstack installer script "stack.sh" functions on the assumption that the devstack deployment is ephemeral. Basically there is no persistence. When you reboot, the software will still reside locally on the disk, but there are no supporting startup routines setup in init or upstart or what have you. The accepted method of dealing with this is to run "unstack.sh" which will remove the previous devstack configuration. Then running "stack.sh" again after that.

@@it4allTN thank you, but i install openstack wallaby on centos 8 stream with packstack, not with devstack

no, it is not mandatory to install openstack on top of vm, but the idea here is to install openstack on your laptop and this is not possible without having vmware workstation or virtualbox. at the same time it is possible if you have already linux running on your laptop to install it directly

@@it4allTN thanks for your reply

@@kayeshparvez you are welcome

try to install devstack on ubuntu 20.04 it is more stable

to install openstack you need in any case a linux operating system that's why you must have a vm running linux. if you want you can install ubuntu directly in your pc or laptop and after that installa openstack

@@it4allTN VMWare integrated openstack I think is installed on ESXi

@@johnnieli2333 but here we are talking about using vmware workstation to install openstack on your laptop or your pc

if you are not obliged to use ubuntu version 18 then try to use ubuntu 20.04 because the openstack installation will be more clean without issues

Have you succeeded moving your vm using this tool?

thank you for your support. this is my personal email address rhim.mohamed@gmail.com if you want to discuss

Thank you for the support 🙏

Pro trick : watch movies at flixzone. Me and my gf have been using it for watching a lot of movies during the lockdown.

@Zyaire Heath yea, been watching on Flixzone for months myself :)

sorry?

hi are you working with vmware workstation? are you using windows or linux or macos?

@@it4allTN I am working winth ubuntu linux 18.04 which is installed on Vmware

@@akshaymewada2321 Chown will work on ext2/3/4 formats but if you are trying to do this on fat16/32 or ntfs it will give you the message you are getting

@@akshaymewada2321 The permissions for non-linux filesystems are defined for the whole partition at the time it's mounted, and you can change them by configuring the drive in /etc/fstab

@@akshaymewada2321 in my case I am working with vmware workstation installed on windows 10. as you are working on esxi environment you may face other issues

This version which is devstack is an all in one openstack and it is used for lab environment or test purposes. if you want to manage many nodes you need to install a nodes for controller part and other nodes for computing.
