@Aimdev
When you click download config and enter the passphrase, please check if your Safari isn't blocking a pop-up window.

You can check that on the address bar, there should be an icon of two windows overlapped. Press there.

You Sir are a star!!

On the variant of safarii it didn't do as you said, but it did flash up a message for about a second in the address line, so I then went into the settings and enable allow popups.

Its a shame the vendor couldn't come up with an answer, we are reassessing the product at the moment and software is assesd not only the product but also the level of support pre sales.

Thanks again Maverick and have a nice weekend.

@olivierlambert said in Transfer Configs between XOA'a:

Plan A is the right way. Plan B is far more complicated

I totally agree, however as I stated there is no indication of a config file being created so Plan B may be the only way,
so is there a file(s) I can access on the old to update the new instance?

@olivierlambert said in Transfer Configs between XOA'a:

Hello,

1. XOA is not from Git. XOA means Xen Orchestra virtual Appliance (the thing you deploy and we redistribute). XO from Git is called "XO from the sources"
2. Maybe your version from Git was broken or too old, impossible to tell. But it should work to export there and import in your XOA.

Thanks for the clarification. To be honest I don't know how it was installed.

Plan A

Where is the config file placed on the operating system, for example using safari, it typicall down loads to the Download directory?

Basically I followed these instructins from the web site
If you still use the first XOA (which was not the "unified" version), you can easily migrate all your settings (ACLs, users, servers, etc) to the new version painlessly.

To do so, go into "Settings/Config" of your old XOA. Export the configuration: you'll download a config.json file.

Plan B

Assuming I cannot get a config from the old system by the export/import method, is there a file I can transfer from the old to the new instance of Xen Orchestra virtual Appliance

Some time ago I installed xoa using git, and I was never able to create a config. Click save config resulted with no action. This was apparent with or without a key.

I have just installed using the import method (btw both the web and bash procedures failed to complete due to a network timeout, but downloading the xva worked)

I have access to both versions, is it possible to transfer the extensive configuration on the older xoa to the new one?

@olivierlambert
Using the old backup system, based on bash/cron never had an issue from pre xpp-ng to 8.2.
Trying out XOA to see if the backup regime would be easier to administer for other users, it failed on the VM with USB.
I do not know if the issue is with 8.1 or 8.2 as I never tested backup with XOA until I installed 8.2 this week.
I also do not know if it is an XOA issue.
You know my thoughts on USB handling as I have commented many times.

@danp

Thanks, comment raised on github.

I built XO today, no errors.
I then exported a VM, no issues.
I then exported another VM, and got this message

All backups via SMB to Truenas (NFS I cannot get to work)
The VM in question has pass thru for a Ublox usb GPS receiver.

Hypervisor for the succesfull backup is 8,1, for the failed backup 8.2 (fresh install)

@hannes_5253
This is a failure re getting usb pass through on boot up of VM correctly.
We use GPS usb devices for time keeping and despite hacking the various files (overridden on upgrades/patches etc) this issue has never been resolved despite comments on this board.

UPS & GPS support is important for obvious reasons, and needs an educated review into the problem.

We moved our UPS to a NetBsd server (not a VM, a separate system) and used NUT (added outside the tight xcp-nt regime) to
provide the essential power loss situation of the hypervisors.

Same with GPS, hosted on same BSD system.

Update

I removed all the rules except the allow all in /etc/xensource/usb-policy.conf
The U-blox device was present when running /opt/xensource/libexec/usb_scan.py -d
The device is present when running xe pusb-list
The device is present using xcp-ng centre
The configuration file clearly has an issue for me to resolve.
Followed instructions from @fjen , thanks for your efforts.
got this on vm startup

It appears the only way to get this to work is via the cli.

Doing a reboot test next, fingers crossed, yes ok

Thanks

Hi

Didn't survive the 7.5 RC1 to 7.5 upgrade, had to re configure it.
All working ok.

@fjen said in XCP-ng 7.5.0 Release Candidate:

@aimdev

Just wanted to chime in here and say that USB Passthrough is also non-functional for me. Can't pass through a USB Bluetooth dongle, even though I added an allow run to the usb-policy.conf file and it shows up fine in the CLI and XCP-ng Center.

Hi

Thanks for the info.

My /etc/xensource/usb-policy.conf contained a DENY for class 2 devices

DENY: vid=17e9 # All DisplayLink USB displays
#DENY: class=02 # Communications and CDC-Control
ALLOW: class=02 subclass=02 # Communications and CDC-Control
ALLOW:vid=056a pid=0315 class=03 # Wacom Intuos tablet
ALLOW:vid=056a pid=0314 class=03 # Wacom Intuos tablet
ALLOW:vid=056a pid=00fb class=03 # Wacom DTU tablet
DENY: class=03 subclass=01 prot=01 # HID Boot keyboards
DENY: class=03 subclass=01 prot=02 # HID Boot mice
DENY: class=0a # CDC-Data
DENY: class=0b # Smartcard
DENY: class=e0 # Wireless controller
DENY: class=ef subclass=04 # Miscellaneous network devices
ALLOW:vid=1546 pid=01a8 class=02 # Ublox
ALLOW: # Otherwise allow everything else

My device is a class 2 device.
Aug 2 06:02:38 localhost usb_scan.py DEBUG: UsbDevice: (u'3-2', {'idVendor': '1546', 'ID_VENDOR_FROM_DATABASE': u'U-Blox AG', 'bConfigurationValue': '1', 'bDeviceClass': '02', 'ID_MODEL_FROM_DATABASE': '', 'version': ' 1.10', 'idProduct': '01a8', 'bNumInterfaces': ' 2', 'serial': '', 'bcdDevice': '0301'})#012#011|__ UsbInterface: (u'3-2:1.0', {'bInterfaceNumber': '00', 'bInterfaceClass': '02', 'bInterfaceProtocol': '01', 'bInterfaceSubClass': '02'})#012#011|__ UsbInterface: (u'3-2:1.1', {'bInterfaceNumber': '01', 'bInterfaceClass': '0a', 'bInterfaceProtocol': 'ff', 'bInterfaceSubClass': '00'})

I commented out the DENY, added an ALLOW for class 2, added the line for the UBLOX, which basically is a serial
device (its a gps receiver I am going to use as the source for a time server)

Rebooted

The result of the /opt/xensource/libexec/usb_scan.py -d command does not show the UBLOX, only the UPS.

Not sure if I have got the configuration correct.
I looked at the citrix docs, but until the scan shows the device, I cannot proceed any further.
I will take a look at the usb_scan.py to try and determine the rules.

Thanks

Aimee

@olivierlambert
Hi

It would appear usb pass through is non functional, which is a shame.
My only options are

1. Plan A, wait untill it is fixed, is this probable?
2. Plan B, install the software on the hypervisor, not good, but probably feasible (freenas is a bit like this, but it is possible as extra's are placed in a protected area
   and do not get disabled though updates)
3. Plan C Raspberry Pi.

Thanks

Aimee

@olivierlambert
Hi

I do not quite understand your answer, please can you clarify.
The system was clean installed from 7.4, 7.41 to 7.5, all xcp-ng.
The ony addition was the ups yum , as described in my thread.
Are you suggesting that a clean install will

1. fix the pass through for the Ublox?
2. To get ups support I must repeat my extra ups software install,?
   unless xcp-ng is going to provide an alternative package for UPS support?

Thanks

Aimee

@olivierlambert said in XCP-ng 7.5.0 Release Candidate:

@Aimdev

I'm not sure to get everything you wrote here.

1. mv: cannot stat ‘/usr/sbin/lvmetad’: No such file or directory is identified and reported to Citrix. It's not XCP-ng specific.
   Ok
2. What do you mean by "test connection"?
   The hypervisor successfully connected to the NAS, for the purpose of importing a saved VM. The VM started OK.
3. Does USB passthrough worked before on 7.4.1?
   Only showed the UPS usb device, never the U-Blox AG , this is the same situation with 7.5 (Thread USB Passthrough 20 Jun 2018, 14:13)
   Both versions show the device U-Blox AG using the lsusb command.
4. What kind of modification did you do on 7.4.1 before updating? was it "vanilla" or you installed/configured some stuff on it?
   Installed apupsd (Thread Apcupsd UPS support 15 Apr 2018, 17:33)
   The upgrade appears to have removed the apcupsd daemon, /usr/sbin/apcupsd, but not the service definition
   7.5

Citrix did not support apcupsd, but Citrix upgrades in the past did not remove it.

5. apcupsd doesn't sound coming from vanilla XCP-ng
   No, but ups support is essential for safeguarding the system.

@r1
Hi

Thanks for that.

Aimee

Hi

Please can someone tell me what family the core of xcp-ng is, suse, centos etc

uname -a gives

Linux netserver 4.4.0+10 #1 SMP Mon Feb 19 10:31:57 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Reason, I wish to install collectd to enable system monitoring using grafana (grafana is on another system, collectd needs to run on the hypervisor)

Thanks
