Error in API Reference - Python on ntnx_vmm_py_client.AssociateVmCategoriesParams()

Hi i don’t know where to report this(no feedback menu on Redocly), but since people may encounter this issue too, i guess they may land here while searching for a solution. As of 11 April 2025, there is an error in the documentation of APIv4 (python version) with regard to associating categories to a VM.The page is here: https://developers.nutanix.com/api-reference?namespace=vmm&version=v4.0 The example code says at one line: associateVmCategoriesParams = ntnx_vmm_py_client.AssociateVmCategoriesParams() well, upon investigating the ntnx_vmm_py_client libraries, i’ve noticed that the class AssociateVmCategoriesParams is imported using AS, therefore with different names depending on technology, as follows: from ntnx_vmm_py_client.models.vmm.v4.ahv.config.AssociateVmCategoriesParams import AssociateVmCategoriesParams as AhvConfigAssociateVmCategoriesParamsfrom ntnx_vmm_py_client.models.vmm.v4.ahv.config.DisassociateVmCategoriesParams import DisassociateVmCategoriesParams as AhvConfigDisas

Where is LACP in ovs-vsctl show ?

I am curious why the running “ovs-vsctl show” on a AHV host does not show any “bond” whereas the “ovsdb-client dump | grep -i lacp” command and the Prism GUI show lacp is present (the switch too) ? Here is the GUI view full “ovs-vsctl show” output from AHV host: [root@NTNX-895b5886-A ~]# ovs-vsctl show84a00041-1b46-44f0-99a1-01a0b1a66713 Bridge br.mx Port br.mx.u.br1 Interface br.mx.u.br1 type: patch options: {peer=br1.local.d} Port br.mx.u.br2 Interface br.mx.u.br2 type: patch options: {peer=br2.local.d} Port br.mx.u.br0 Interface br.mx.u.br0 type: patch options: {peer=br0.local.d} Port br.mx Interface br.mx type: internal Port br.mx.d Interface br.mx.d type: patch options: {peer=br.microseg.u} Bridge br.dmx Port br.dmx Interface br.dmx type: internal Port br.dmx.u Interface br.dmx.u type: patch options: {peer=br.nf.d} Port br.dmx.d.br0 Interface br.dmx.d.br0 type: patch options: {peer=br0.u} Port br.dmx.d.br2 Interface br.dmx.d.br2 type: patch options: {peer=br2.u} Port br.dmx.d.br1

Memory impact on rolling upgrade

Hi all… I have 3 node DX cluster with around 50 VMs powered on residing on AHV. We are planned for a rolling upgrade, CPU and storage resources are good enough. However, memory utilization is a concern: Memory of powered on VM = 690GB Memory of powered off VM = 210GB Memory usage 91% Total pRAM = 754GB RAM Will this be risky for a rolling upgrade given that no pRAM is added and no VM planned to power off?

Deskmini A 300へのNutanix CE2.1インストール時のiSERポートエラーについての相談

以前に同じ質問をさせていただいたのですが、その後自身で様々な方法を確認しても自体が好転せず他に方法がなくなってしまったため、同じ内容の質問とはなってしまいますが、改めて質問をさせていただきます。以前の質問の通り、Deskmini A 300にNutanix CE2.1をインストールすると、 setup_rdma.py[8310]: INFO:rdma:No Ports reserved for iSER on the node. Exiting! と表示されてしまい動作が停止してしまいます。これはDeskmini A 300に起因する問題なのでしょうか?あるいは他に修復方法があるのでしょうか? 参考までに、Proxmox等の他の仮想マシンは動作を確認する事ができました。以下、以前の質問文です。現在、Deskmini A 300を使用してNutanix のCE2.1版をインストールしようとしています。インストール自体は完了するのですが、その後再起動すると setup_rdma.py[8310]: INFO:rdma:No Ports reserved for iSER on the node. Exiting! という表示が出て、CVMにアクセスする事ができません。そもそもPing自体も失敗してしまいました。(AHVはPing可能でした) 調べてみたのですが、情報が全くヒットしなかったため、めずらしい問題が発生してしまったと考え、こちらに相談をさせていただきました。どなたか、同じような症状が発生した方や解決できた方はいらっしゃるでしょうか。マシン構成の詳細は、 CPU:AMD Ryzen5 2400G メモリ:corsair VENGEANCE(DDR4-2666) 16GB * 2枚ストレージ CVM Samsung SSD 970 EVO Plus 500GB ハイパーバイザ WestanDigital Blue SA510 250GB データ TOSHIBA MQ04ABD20 (データ WestanDigital EAAZ-00BXBB0)(USB外付けHDDのため動作確認のため使用停止中) となり、残りの構成は、DeskMini A300の初期構成のままとなっています。

Nutanix CE installation hang up to a shell

I tried installing Nutanix CE. Created boot USB with rufus, booted and the installation starter. I can see NIC are looking for IP addresses, and one of the interfaces receives an IP from DHCP server. After some time I get the error message with starting a service: [FAILED] Failed to start Systems Management Device Drivers After that the installation hang up to a shell with some Python related error: SyntaxWarning: “is not” with a literal. Did you mean “!=”? I know this is just a warning message, but I have there several lines of error ending with: AttributeError: ‘NoneType’ object has no attribute ‘dev’ The server is R630 with two CPUs, 4x NIC (Broadcom and 2x 10Gb Intel (where the network cable is plugged in).

How to increase the sinze of Prism Central?

In this single-node hardware environment (24C/384GB/4x800GB) I have installed Nutanix CE 2.1 which work fine. I then wanted to test Prism Central and deployed it in size x-small which turned out to be too small (could not do all fun stuff). How do I increase it to size small instaead? I tried to just add the extra cpus and memory to match the size of small, but that was not enough, it still said that it was x-small. Then I tried to remove PC to create a new larger one, but it wasn’t as easy as I thought. The VM wasn’t possible to delete without deregister but the deregister was blocked but a objects-lite database which wasn’t possible to remove! It just referred to KB-17159 which literally only said “Contact Nutanix support”… But this is CE and I’m just a partner playing around without support… Any procedure for size upgrade of Prism Central? (I searched in the portal but failed)
