  1. prevent take over of a SPICE-Remotedesktop

    i#m now going forward with a combination of Hyper-V and guacamole. Guacamole can connect to Host-RDP of Hyper-V and has some of the features that MS removed with Server 2012R2 (permission per users) which gave a similar experience then with Virtualbox. Unfortunatly Proxmox seems not to be...
  2. prevent take over of a SPICE-Remotedesktop

    Well, not really. I need the Host-Remotedesktop because of the workload i have running & it is possible somehow, as Virtualbox shows. In Virtualbox you can limit the amount of parallel user via settings to one user, preventing the overtake of a Remotedesktopsession. Not really a perfect...
  3. prevent take over of a SPICE-Remotedesktop

    No one even has a idea to prevent the overtake of a remote session?
  4. prevent take over of a SPICE-Remotedesktop

    Hello, is it possible to prevent the take over of a existing SPICE remote desktop session? Actually, every user with permissions to a dedicated VM can over take any SPICE Window that another user with similar permissions had used. And therefore spy on any data and use the login on those VM by...
  5. SPICE Verbindung auf einen User beschränken / SPICE privacy?

    Hallo, für einen sehr speziellen Anwendungsfall brauche ich eine Art VDI Lösung die aber privatheit ermöglicht. Es sollte also NICHT möglich sein das jemand die Remotekonsole/SPICE-Fenster einer VM übernimmt und dadurch ein Login (auf der VM) einfach übernimmt und auf die dortigen Daten...
  6. VM cloning with zvol-volumes TERRIBLE slow

    The HDs are a completely wrong type for that workload. In fact they have not been bought for this, but for backup like purpose to store the Tranaction log backups of the S4/HANA system. I have used them now for the VM cloning because i did not had anything else and the cloned VM was only for...
  7. VM cloning with zvol-volumes TERRIBLE slow

    The system is in use now since some days. It's a refurbished HP Proliant box. Have not seen anything wrong. Only ONE VM (a S4/HANA) which i try now to clone. No, i did not changed anything of the ZFS parameters. But i installed PROXMOX OS over al already installed and somehow messed up older...
  8. VM cloning with zvol-volumes TERRIBLE slow

    ok, you are right. I should check first for the bootleneek well, then, it reads from zpool ZFS-SSD and writes to zpool ZFS-SSD root@Mypve:/ZFS-HDD# zpool iostat ZFS-SSD 5 capacity operations bandwidth pool alloc free read write read write ---------- ----- ----- -----...
  9. "isolating/hiding" a VM with ip overlapping from LAN network with NAT

    OK, because i#m curious about this thing i now tried it under hyperV with a pfsense vm as NAT device. I managed to configure the pfsense with the same network ranges on both sides, created a portforwarding and tested it. But in the end i did not got any response via the forwarded port. And now...
  10. VM cloning with zvol-volumes TERRIBLE slow

    But i thin k i gave up now and first buy some additional SSDs to replace the HDDs. Just one question. How to stop the cloning without braking anything? Can i just kill the qemu-img convert process? In the GUI there seems to be no way to stop the cloning.
  11. VM cloning with zvol-volumes TERRIBLE slow

    Just to compare the actual results. The source VM that i#m cloning actually, has been imported some days before from a KVM Box to the actual Proxmox host. I copied the original qcow2 images on the HDDs before converting them into the SSD-zvol. Those copy of the qcow2 images was MUCH faster then...
  12. VM cloning with zvol-volumes TERRIBLE slow

    Well, as i see it just shows me that it is really slow. OK, i knew the HDD RAID1 is not a rocket. But the ONLY task that is running on those HDDs is the qemu-img convert. Nothing else on this HDDs and no other VM running. Idling around ..... Even if i expect only 50% performance off ZFS-write...
  13. VM cloning with zvol-volumes TERRIBLE slow

    Hello, i#m actually cloning (offline copy) a VM with 125GB RAM (yeah, really, a HANA setup) and three 300GB zvol-volumes from a (ZVOL-SSD to a ZVOL-HDD). After 8h running, not even one zvol got copied. When i look into iotop, i see that there are some qemu-img convert running, each with a write...
  14. "isolating/hiding" a VM with ip overlapping from LAN network with NAT

    OK, Cisco uses a perimeter network with two routers. This is the setup if you need to connect two networks.
  15. "isolating/hiding" a VM with ip overlapping from LAN network with NAT

    Well, i know it's not common to use ip overlapping networks, but in fact it's possible and also in the official RFC. I have done it easily before in a Virtualbox envoironment, also i have done it more often with a physical pfsense-Box as NAT device. But the only good documentation you find on...
  16. "isolating/hiding" a VM with ip overlapping from LAN network with NAT

    if i create a new NAT network with the IP from the LAN network, i got a error but somehow it should be possible to do such stuff, as it happens sometimes in hosting environments.
  17. "isolating/hiding" a VM with ip overlapping from LAN network with NAT

    Hello, for some test scenarios i need to isolate a copy of VM from the network itself but still need to be access it via dedicated ports. Example. Proxmox host: 192.168.0.10/24 I have a VM0 (bridged) with IP 192.168.0.1 in a LAN with network 192.168.0.0/24 and LAN gateway 192.168.0.254. Now i...
  18. Proxmox CIFS Store "ISO"-only as "Read-Only" possible?

    OK, i now hacked around a little bit about those restrictions, but in the end, well, such a scenario is not supported by Proxmox even if i think this is often seen. i now created a local mountpoint /mnt/OS/template/iso and mounted my Share (which holds all iso in subfolders) into it. Then i...
  19. Proxmox CIFS Store "ISO"-only as "Read-Only" possible?

    OK, i also tried now a second way. Mounting the CIFS-share manually in a mount-point at Proxmox OS-level and then adding a "Folder"-Storage in Proxmox-GUI. However, it again showed the same problems Proxmox ALWAYS tries to create his own folder structure (e.g. /mountpoint/templates/iso) below...
  20. Moving Backups between storage

    Hello i#m reconfiguring our Storage. Therefore i need to move some VM-Backups from one storage to another. Is this possible from the GUI at all? (Didn#t found :-( ) If i do it via cmdline, is there anything i need to do that after it shows correct in the GUI? Thank you.
