    To elaborate: it was already in progress, but delayed due to 1. the fact that I underestimated the impact (I thought we'd overwrite the file only when we'd modify it, not every update the package) and 2. lots of other priorities keeping the team busy. But it's clearly the reminder, and the help in better diagnosing it, that allowed to have it re-prioritized and (partly, we've mostly bought time to fix it properly, by simply avoiding to touch the file at all at the moment) fixed so fast.

    It's not meant to be used like that. If you are behind a NAT, the right approach is to have your XOA behind the NAT and inside the same network than the hosts. That's because hosts will always use and return their internal IPs to connect to some resources (stats, consoles etc.). XOA deals with that easily as being the "main control point" for all hosts behind your NAT (or a XO proxy if you prefer).

    @florent said in vmware vm migration: @acebmxer yes after the first migration, XO knwo that the migration is incomplete and that you may want to finish it later. But if you start this VM direvtly , it will write some data, thus it won't be in sync anymore with the Vmware snapshot. Then XO won't be able to resume You can start a copy of the VM ( XO will handle it for you ) and delete the copy when you're done My advice is to migrate this VM to the right SR and then do the resume. But keep in mind that the V2V tool is intended to target only one SR, so migrate all they disk to the same SR, and select the right one when resuming the V2V. You can change the network after My previous migration was successful with no issues. Previously test vm was fresh install so no vmtools installed. But I did shut the vm down myself prior to starting the migration. VM boots no issues no prompts. This time I decided to follow the steps listed in the documentation as i have been following the changes and updates for the v2v migration. Following the steps as mention XO presented me with that prompt which was not mention in the documentation. As i was typing the post to gather my information it was then i noticed i did not select the proper destination SR and the appropriate nic/vlan for networking. So I noted that in the post. With the assumption i could correct that on the final migration. With that said the I guess the documentation should state - Start vm to test if boots, etc.. When prompted choose "Start a copy". When done shutdown vm and remove.

    Hi everyone, I’m currently working with XCP-ng 8.3 (fully updated) on a Dell PowerEdge R720 in my homelab, and I’m trying to access the iDRAC interface of the same server from a Debian 12 VM using ipmitool. I want to use the OS-to-iDRAC Pass-Through feature (USB NIC) to allow the VM to communicate directly with the iDRAC, so I can run ipmitool commands like power status, fan control, etc., from within the VM without going over the network (which is segmented off). What is working The iDRAC Pass-Through feature is enabled in the iDRAC web interface under: iDRAC Settings → Network → OS to iDRAC Pass-Through (USB NIC set to the IP: 169.254.0.1) The iDRAC network test confirms it’s working. The pass-through interface (PIF) appears in XCP-ng’s host network list as idrac. I’ve attached it to a Debian 12 VM, where it shows up as enX1. The VM has correctly assigned 169.254.0.2/24 via /etc/network/interfaces. Despite the correct IP assignment, I cannot ping 169.254.0.1 from the VM: # Output of ip a (shortened) 3: enX1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether d6:24:9e:46:de:64 brd ff:ff:ff:ff:ff:ff inet 169.254.0.2/24 brd 169.254.0.255 scope global enX1 ping 169.254.0.1 # Output: # From 169.254.0.2 icmp_seq=1 Destination Host Unreachable # (repeats) And ipmitool fails with: ipmitool -I lanplus -H 169.254.0.1 -U <user> -P <password> power status # Error: Unable to establish IPMI v2 / RMCP+ session Tested the same as a bare metal setup on another R720 with Debian 12 and that worked as expected. I have a distinct feeling that I have asked this question before, but unfortunately I can't find the post anymore. Any insights, tips, or similar experiences would be greatly appreciated!

    @Danp yes I ran "yum update" to be sure but "nothing to upgrade" on the pool-master. I try with storage (iscsi) NIC configured and without Storage NIC configured but the pool join freeze. Seems that persist some "SESSION" (may be referred to the slave host previously configured?) or some incoerence in the pool database... from /var/log/xensource of the slave host when try to join the pool: "session_check D:520c5b4e5b36 failed with exception Server_error(SESSION_INVALID, "

    @olivierlambert Agreed. The Citrix forum used to be very active, but especially since Citrix was taken over, https://community.citrix.com has had way less activity, sadly. It's still gratifying that a lot of the functionality still is common to both platforms, although as XCP-ng evolves, there will be continually less commonality.

    For anything older than the branches still shown in https://pkgs.alpinelinux.org, (from v3.0 to v3.12), the packages should be downloaded from their cdn: https://dl-cdn.alpinelinux.org/alpine But as mentioned above, anything older than 3 releases from the lastest current one(v3.21) are end of life and should not be used for more than testing.

    @vkeven XCP-ng 8.1 release note says VSS and quiesced snapshots support is removed, because it never worked correctly and caused more harm than good. Note that Windows guest tools version 9 (the default for recent versions of Windows if you install Citrix drivers) already removed VSS support, even for older versions of CH / XCP-ng I am not sure if this VSS feature is bound to the PV drivers, or if it also needs hypervisor support. Though it is not recommended to stay on a old version of the guest agent.

    @olivierlambert @olivierlambert said in Diagnosing frequent crashes on host: Maybe there's a usage that's slightly different since when it was "more solid" and now it's trigger more easily. Is your XCP-ng fully up to date? No; as said originally, I'm still on 8.2.1. I have been concerned about moving to 8.3 because it's a new installation, and I don't want to screw it up, but I'm willing to accept that it's the right thing to do.

    reboot of host does it stop or kill running VM's?

    Could someone elaborate on the procedure to have all VMs on a host shutdown properly upon XCP-NG host shutdown please? I tried from the host prompt: xe host-disable xe host-shutdown and from XOA Host: shutdown, with warning (This will shutdown your host without evacuating its VMs. Do you want to continue?) and rightly so the host has seemingly become unavailable (ping to its IP stops) But then what happens is very odd: first the VM on it still pings for a couple minutes (yes after the host stops to answers the ping) then the VM stops pinging but AFAICS XCP-NG is not OFF Awkwardly, I just access to the IDRAC8 entreprise license on which XCP-Ng is running, and can't SEE the proper status of XCP-NG from it. AFAIK it's not pinging but it doesn't seem OFF either. At least the IDRAC shows it ON, and upon power cycling and reconnecting to the VM the logs shows it hasn't been cleanly shutdown. NB: the VM has xen-guest-agent running within a container, but from what I gathered, the agent in Linux guests has no role in VM shutdown: See https://xcp-ng.org/forum/topic/10631/understanding-xe-guest-utilities/16 Also, I doubled check Proxmox: it does clean shutdown VMs, either with a "shutdown -h now" command or when triggered from GUI. And that's with a VM that has Promox guest installed. In any case, it would be nice to have XCP-NG/XOA be able to do the same.

    @olivierlambert I was looking for a way to mark this solved, can't find it. I haven't moved things, but after migrating my big lab to my mini-lab, I'm confident that the warm migration is the way to go. It was fast and seamless as long as you have the right network adapters set up. I had to fool with one of my networks to make a VM function, but that was certainly something I overlooked while setting up the mini-lab. A little testing before moving the VMs should make this go easily if using the old servers is the option for this project.

    @MAnon This is a valid point actually, and without additional work, you couldn't just restore to another hypervisor. However, check this blog post: https://xen-orchestra.com/blog/xen-orchestra-5-100/?utm_campaign=mail_5.100&utm_term=logo&ct=YTo1OntzOjY6InNvdXJjZSI7YToyOntpOjA7czo1OiJlbWFpbCI7aToxO2k6NjU7fXM6NToiZW1haWwiO2k6NjU7czo0OiJzdGF0IjtzOjIyOiI2NzIzODI1NDE4ZjVmMjE5NDI2OTYwIjtzOjQ6ImxlYWQiO3M6NToiODM5ODciO3M6NzoiY2hhbm5lbCI7YToxOntzOjU6ImVtYWlsIjtpOjY1O319 Veeam is likely going to properly support XCP-ng. And for what it's worth, you can use agent based Veeam backups in the VMs and that works fine.
