I know that difference but in backup process incremental snapshot using zfs send / zfs receive time is also the same.
Maybe PBS/PBS Client dev should use other magic spells for backuping LXC?
Well - doing incremental backup I see that comparing backups VM(1TB) and LXC(800GB) speed there is 10x performance gap (or even more! - doing backup for LXC is significantly slower even if it's smaller)
I did some test zfs send/zfs receive to remote host not differs so much.
Local storage...
Sorry. Dictionary in my Phone made bad things sometimes. I mean PLP technology - capacitor on SSD Drive. That allows to scream by ssd "write done" before it is done because it save.
Check pvestat command on both drives.
I tried to juggle cards with different PCI-E - it didn't help.
When I turn on second network device (no matter whitch) it gives me an error:
genirq: Flags mismatch irq 16. 00000000 (vfio-intx(0000:88:00.0)) vs. 00000000 (vfio-intx(0000:05:00.0))
It looks like some race condition bug when I...
When I am trying to start VM with passtrough two network devices there are errors in DMESG:
root@rtx-proxmox:~# dmesg | grep 'Flags mismatch'
[ 99.938242] genirq: Flags mismatch irq 16. 00000080 (vfio-intx(0000:81:00.0)) vs. 00000000 (vfio-intx(0000:08:00.0))
[ 302.258175] genirq: Flags...
The other thing I tried is add another virtual machine and passthrough second device at the same time.
It doesn't worked.
Do this matter if the devices got the same IRQ's:
88:00.0 Ethernet controller: Mellanox Technologies MT27500 Family [ConnectX-3]
Physical Slot: 4
IOMMU group: 100...
Yes - I checked it twice. Name of module is like blacklist module inside conf file.
I attached my lspci for more info.
Most important thing:
1. Kernel driver in use: vfio-pci
Kernel modules: ixgbe
2. Kernel driver in use: vfio-pci
Kernel modules: mlx4_core
So that means that is...
@oguz did You read one mail infromation from my post about that VM is starting when only one device (no matter whitch) is set for passthrough?
In my /etc/modprobe.d/ I've got:
-rw-r--r-- 1 root root 16 Jun 1 11:36 ixgbe.conf
-rw-r--r-- 1 root root 20 Jun 1 11:36 mlx4_core.conf
-rw-r--r--...
I tried to passthrough PCI device alone:
I tried to passthrough another PCI device also alone:
Then I tried to Passthrough together two devices:
And I've got:
kvm: -device vfio-pci,host=0000:81:00.0,id=hostpci1.0,bus=pci.0,addr=0x11.0,multifunction=on: vfio 0000:81:00.0: Failed to set...
Networking stack is complex - adding additional layer for this would block the oportuninty of tuning in many ways.
So I think I probbably use IOMMU instead of SRV-IO and not to use virtio as a bridge to network nic.
