@lawrencesystems Hi Tom...yessir...I'm just testing out XO. I do have XC and just "looked" at it, but am not doing any configurations, etc in it. It was more to see what it looked like. Again, all my testing will be within XO. Thanks.

I knew (from your vids, actually) Xen has been around awhile, but I guess I wasn't aware XO has been. Thought that's only been out about 5yrs or so. I'm still frustrated at my testings so far, but not giving up. Hopefully my continued testing come next wk will result in more positive outcomes fingers crossed

Thanks for reaching out!

@lawrencesystems Hi Tom....I actually have watched several of your vids. Thanks for them! I've been in virtualization for quite some time, so I have a decent general understanding; altho, I understand each h/v has its own quirks/bumps. I have also been reading thru both XCP and XO docs. There isn't much details in them tbh. But again, there isn't too much in Xen central mgmt tools either.

I know Xen's been around a while, as well as its central mgmt (XenCenter), but XO hasn't (really). Pools in XO seem to be kind of klunky; at least it's been that way to me playing around in it. I've rebuilt my 2 Hosts again for a 3rd time and re-added them to XO. I have yet to consolidate them into 1 single Pool again though. I'll re-attempt things again on Mon. One thing which "may" have caused issues I wasn't fully aware of -> patch installs. I did install them initially, but the msg that pops up says the Host reboots, and in actuality..it doesn't. This time around, I did manually reboot them. Maybe that caused issues?...not sure. Although...I did end up rebooting one of my Hosts multiple times in my prev testings, but that didn't rectify any issues I was having (but I didn't reboot my Master).

I'll update here if I continue to have issues. Thanks!

I'm in the early stages of testing XCP/XO (on Sources) for possible VMW migration in the future. I have to say...so far, I'm not at all impressed. I haven't even started creating VMs yet and am having all sorts of "bugginess"..just with Pools.

First, I like the fact when adding Hosts to a Pool, and making Network or Storage changes/adds, the change is applied to all Hosts in a Pool. Cool! Aside from that, Pool mgmt just seems to be buggy. Any explanation is appreciated.

My test setup is simplistic:

2 Dell Proliant DL360 G9 Hosts, XCP-NG 8.3 installed via ISO. Easy enough. 2 HBA cards using just 1 port on each for now...1 10Gb port for Mgmt & other networks, and 1 10Gb port on 2nd card for iSCSI storage connection
An Ubuntu 24.04 VM with XO via Sources installed. Again, fairly easy. All good so far.
I then was looking at Storage steps (adding iSCSI) and configuring my Networking to see my SAN & adding an IP to a HBA was not really intuitive at all. Found a post on here to help me through that...after 2hrs of clicking around
So, I think I have my Storage and Networking squared away. Now just needed to create a Pool and get my Hosts in one. This has been klunky to say the least; 1. in how it's done, then 2. Host behavior when in a Pool.
a. Add 2 Hosts to XO. Ok
b. Click Host1 and "go into" its Pool. Change the "Name" to give a more appropriate Pool name for multiple Hosts. Ok (but still a bit klunky in how this works)
c. When in this new Pool, add my Host2 to it. Ok (so far)
d. My Master (Host1) seems to be fine in the Pool; my newly added Slave (Host2) is "yellow" status. It says 'busy'. I go to Advanced tab to try to Enable and it won't (why it isn't already Enabled, I don't know). Host2 also appears to be in Maint Mode. Why? If I click on "Disable Maint Mode" button, it has the same behavior as when I try the "Enable" button...nothing. I can't even 'Detach' this Host2 from the Pool And, this is the 2nd time I've tried these steps. When I was clicking around the 1st time with Pools, my Host2 showed all RAM used (nothing is on any Host) and showed as "halted" or "offline". I ended up reinstalling XCP 8.3 and re-adding to XO. Took care of those error things, but again...still not acting right this time either. Also, does Slave Hosts take the root pwd of the Master? I'm noticing that behavior as well. How is that possible? That isn't a good thing imo. And now, it appears my Host2 lost it's mgmt nic configuration...so another reinstall will seemingly need to happen

And again, I'm just in the setup pieces...not even testing VM creation and management. I really do want this to work ok so I can eventually leave VMW, but I'm not at all confident in this h/v solution to this point. Isn't this supposed to be "stable"? I have my doubts Any suggestions appreciated...

@olivierlambert Ah, ok...thanks, but I'm not using the appliance; I installed XO via source.

@olivierlambert How do I do that? I am literally new to XCP/XO x 1 week

@olivierlambert FYI Olivier (sorry, I know this topic is closed, but I had the exact issue as @dsiminiuk did and this thread helped me...kind of)... the UI is very suboptimal imo. Clicking the Host in and of itself doesn't show the options (Mode column) in the Network tab as you share above. If you click the "link" Host on the far right in Home > Hosts, or Settings > Servers, you don't get the needed columns to make the IP change. You have to click the Host name on the LEFT side to see a different set of options in the tabs. Very confusing IMO.

I just installed XO on source today (commit 224c8). I saw a couple days ago that it looks like you all just released a newer XO version with a view like that of XenCenter (or vCenter)? Is that accurate? If so, XO is in desperate need of a View like that. I'm playing around with XCP in hopes it can be a sufficient h/v for us to migrate to away from VMW for obvious reasons (we're an SMB). Major factor to this point is no Veeam integration..once that's set, I'll look harder.

I hope you all keep developing good things in XO.
Thanks.
