I don't know if Ubuntu (well AppArmor) has support for this or not, but if you have selinux, you should also have policies for the container itself. CoreOS does this automatically (svirt and selinux), as does RHEL/Fedora, through container-selinux

Question, I've been tasked to clone a virtual machine running some old lovely software so that they can mess around on the clone without affecting the production machine. We don't have a dev environment/network so this machine would run along side the other one on the same network but with just different IP and hostname. How do I actually achieve this in vCenter 6.0? I know there is a clone button but I've been reading that I need to edit the .vmx file after cloning and change the UUID and other people have said I need to sysprep the machine after the clone. Can anyone clarify the exact process of cloning a VM and bringing it up on the same network? edit: Also we have Veeam B&R 9.5u3, can I skip the whole vCenter thing and bring a copy up with this instead? kiwid fucked around with this message at 22:00 on Jul 12, 2018 |

Veeam can replicate the VM for you, use that to do this. You can re-IP the box as part of the replication task as well. If it's domain joined then bring it up with the network disconnected the first time the replica boots, remove it from the domain, reboot, reconnect the virtual network and then bind to the domain with the new hostname.

You can use the replication job to clone the VM as a one-time thing, you don't need to keep it in sync.

Been having some weird performance problems with my CentOS 7.5 VM on Windows host. It seems like gnome-shell will randomly decide to start consuming 25% of CPU and then everything slows down to a crawl. Tried updating to latest packages, latest VirtualBox, latest windows OS updates, BIOS updates on my laptop, etc. Performance is fine for a little bit after boot, but inevitably turns to molasses.

I'm guessing it's some redraw issue linked with Virtualbox's mediocre 2D/3D acceleration. Maybe try disabling that? Or try a headless VM?

Anyone find themselves extremely frustrated by Solarwinds VMAN? My company got it instead of VSOM because it integrates with Solarwinds Orion, but good Christ what a clunky, unusable abortion of a reporting system this thing has. I for the life of me cannot figure out how to generate an Oversized VM report, but limit it to a cluster AND have it generate recommendations for export to a spreadsheet. Solarwinds product are by far completely unusable by the layman.

Anyone remember what that Powershell PowerCLI script that you can use to gather a whole bunch of information (hba's, vmkernel IPs, etc) across your entire vCenter environment? My brain is failing me right now.

At the last place I was at we had a PowerCLI script that would run daily and send out report of all snapshots. I'm pretty sure whoever set it up just found the script somewhere online but it was good to have alongside alarms.

I've been working on setting up syslogs from a VMware 6.5 environment, and having a bitch of a time with the ESX part (vCenter is going well). In the ESX hosts, I set the variable "Syslog.global.logHost" to poing to my syslog server, enable the firewall rule on the host, and messages pour out. However, the bulk of the messages are "debug", and I couldn't find a way to get them to step down to "info" or even "warning". So I gave up, and reset "Syslog.global.logHost" to blank, disabled the firewall rule for syslog on the host, and even did a "esxcli system syslog reload"... and messages are still flowing to my syslog endpoint, even 2 hours later. Now I'm assuming that I'm missing something obvious, and the same solution to make syslogs stop going out might be the same as changing the effective logging levels. Any ideas?

I did a firmware update on one of my Dell servers. vMotion to the host now takes about half an hour per VM. Away from it takes the normal one or two minutes  VMware support was useless, unsurprisingly. I should have checked with Dell first. I will probably do that Monday...

It's probably not the firmware that did it, more the act of rebooting after applying the update. There might have been a config change pending that didn't get actioned until vSphere came back up.

Check your mtu from end to end, vmkping various sizes, check your vmkrrnel responsible for vmotion, draw everything out on paper, assume nothing. Invariably this comes down to, "oh gently caress did I do that?" in my experience.

Invariably this comes down to, "oh gently caress did I do that?" in my experience. First thing I did. Host A to B vMotions are super slow, but host B to A aren't. That means that MTU and vmkernel aren't it, and vmkpings confirm MTU is fine. I defintely agree that it's probably an "oh gently caress", but I can't find it.

Do you have vmotion enabled on two different vmkernel interfaces? Like, a management interface that is only gigabit instead of 10gbe?

Is the vmotion actually cancelling after an hour, or does it eventually work?

We have separate vMotion vmknics - this one host that is problematic only has 10 GbE to storage, the rest of its interfaces including the vMotion one are 1 Gb. vMotions do finish eventually - there is a log file that indicates they are happening at roughly 2 MB/s. Before this firmware update, everything was working fine, and I didn't make any changes that I'm aware of

Are the vMotion interfaces on the hosts backed by multiple physical adapters? If so try dropping each to a single active adapter and testing with each one active in turn to see if the issue is the same no matter which adapters are used.

Hmm 2MB/s wouldn't actually be all that lovely if you were vmotioning local spinning disk storage under regular load. Except you've probably have centralized storage. Do you see packet loss? http://buildvirtual.net/#article/3174

There were tons of CRC errors on both interfaces and switching the active uplink didn't do anything. We updated the tg3 driver and started using that instead of the ntg3 one and all of a sudden everything works as expected

Okay dumb question about HyperV. From what I'm reading HyperV is a class 1 hypervisor and when it's enabled on Windows, the HyperV kernel is installed as the default booted operating system that will then run your Windows installation as a virtual machine on it. To me this almost implies that I can then patch and reboot that Windows OS without the other virtual machines needing to stop - is that at all true?

No, because the VM services, including device emulation, run in the host partition that you're wanting to reboot.
