@Andrew That's what I thought, but basically wanted confirmation. Are there any settings to look at that may be able to be tuned in XCP to improve responsiveness?

Hi all,

Hi have a supermicro MB with two, E5-2630 v3 processors. For RAM, I have 96GB of DDR4 ECC (Only 32gb in use). My vm's perform somewhat slugishly, so I am looking to make some changes. In everyone's experiences is it better to have more cores or faster clock speed? I'm wondering if going from my current pair of processors to something like the e5-2699 with 22 cores each would make a difference in the responsiveness, or would I better off with something like a 16 core Ryzen?

Any input is appreciated.

@Danp I can agree with that

@Darkbeldin Well if XCP had just told me it was down

@Darkbeldin

It appears that my ISO library got disconnected.

I built a new windows 10 VM, after creation I went to start it and received the below error.

vm.start
{
  "id": "acf54408-dc93-4040-911e-073bf9bdbe4c",
  "bypassMacAddressesCheck": false,
  "force": false
}

  ],
  "message": "",

} 

What doe this error mean?

Thanks

@olivierlambert After the latest update, one of the two VM;s that would not restore now restores successfully. I'm still not sure why the second one won't restore.

@olivierlambert I've opened a tunnel. The ID is 33769. Do you need any other information from me?

@olivierlambert My trial of premium is over, so I am unable to do that.

@olivierlambert

That is correct.

@olivierlambert

XOA is what I have been trying. I have not tried the restore in community.

@olivierlambert

I have both installed to try out community. I am performing the restore from XOA, the same console I used for the backups.

Incidentally, I would pay for the XOA, but $70 a month to get back up for my home lab is a bit pricy, I only have one server. You guys might consider offering a paid version with backup that maybe doesn't include premium support for a reduced price. I can't speak for anyone else, but I would be willing to pay for something like that, to have a turnkey solution with easy updates and backup.

@olivierlambert

Any logs inside XCP-NG that I can look at? I've resigned myself to the fact that I will have to rebuild the two VM's that won't import, but I'd like to prevent a similar situation in the future.

@olivierlambert

Is there anyway to determine whether it's a failed backup or stalled import? Is there anything that can be done to correct a stalled import? I assume there is nothing that can be done for it if it's a failed backup..

Also interesting is that the restores that fail are listed with a number instead of the VM name.

@olivierlambert I'm also trying to restore the VM's that were successfully backed up. I have two that fail to restore and give the error:

IMPORT_ERROR_PREMATURE_EOF()

What can I do to determine what this failure means? I found a previous entry about disk space, but I do not have any disk usage issues that I can see.

Thanks

@olivierlambert

Where would the timeout fix be applied in community edition? There is not a /etc/xo-server directory.

Thanks,

@AtaxyaNetwork I got it to work.

Do you know how to enable console login for this debian install?

@AtaxyaNetwork

I created an SSH key pair with puttygen. When I login with my private key (public key is on the debian VM), I get the messgage "server refused our key."

I used RSA for the key at 2048 bits. Is there something that tells what cipher and bit length to use?

Anyone know the default console login for the Debian template? The details say user = debian , however I can't login at the console without a password.

It looks like changing the time out to 60 minutes has fixed my backup issue. So, the next question.

Is it possible to restore the VM backups to a different install of XCP-NG? I have a single XCP-NG server and would like to re-install XCP-NG and set it up for XCP to be on smaller hard drive and all my VM storage to be on a ZFS RAIDZ1.
