register cli: xo-cli --register http://url login
then remove all tasks: xo-cli rest del tasks

Problem with broken package on rhel8-9 looks resolved now. Done multiple tests.

@DustinB said in New Rust Xen guest tools:

systemctl enable xe

yep, found them.
full steps for RHEL:

wget https://gitlab.com/xen-project/xen-guest-agent/-/jobs/6041608360/artifacts/raw/RPMS/x86_64/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm
rpm -i xen-guest-agent*
yum remove -y xe-guest-utilities-latest
systemctl enable xen-guest-agent.service --now

@chrisfonte new tools will remove the old one during install.

@ckargitest that was fixed few weeks ago. Do you use latest commit?

Fixed now, thanks you.

updated to fix_cbt branch.

CR NBD backup works.
Delta NBD backup works.
just once, so we can't be sure yet.

No broken tasks is generated.

Still confused why CBT toggle is enabled on some VMs.
2 similars vms on same pool, same storage, same ubuntu version. One is enabled automaticaly, other is not.

if you have no any dedicated storage, it's possible to use literally any PC with nfs\smb\external drive, windows share also.

Backups not very fast anyway, because of XAPI limitations. I see cap about 300-400Mbit at 10Gbit local network.

I agree, got a similar dilemma now.
Required to grant permissions to single host (gpu computing) and ability to create\remove VMs.

But it looks it no ACL for VM creation, it available only for global admin\pool admin accounts. So only way is setup standalone XO for each single host? This way i lose the pool storage and VM migration.

@olivierlambert yep, /etc/multipath/conf.d/custom.conf .

weird advice, but i got same problem when XO CR copy started and caused ip conflict with main XO.

disable \ enable works.

@florent also it works too good.
i don' used advanced mode for CR backup, so NBD is disabled for job.

but task is working with nbd)

@florent lets a brief summary.

nbd work only via management interface. If nbd enabled on any another interface and specified as pool backup interface, it don't work (the issue with blocked packets at iptables). That was a main reason of my problem.

For now i made it work at all my pools. Max single thread speed increased 80-90 > 140-150. At usual backup task (when daily delta very small) it show same 10-40Mb, because it done too fast. Average task time decreased fo about twice.

214b8 can't reproduce.

lets talk with direct examples.

and it stuck forever

not a self signed, import works a few weeks ago. Looks like yet one issue after last bad patch.

@itpartner it already builtin at xen 8.3, so guide will not requried.

can't install zabbix on 8.3.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

at 8.2 i only need to enable more repos, but 8.3 already use it own Vates mirror for Centos.
