[ovirt-users] Re: Unstable VM network connectivity after upgrade 4.2.8 to 4.3.7

Hi Lacho, Can you run the virtio drivers ?  They are the most tested in KVM . Also, can you run a tcpdump (with e1000) and check what is going on when the network disapperead?  Best Regards,Strahil Nikolov В неделя, 12 януари 2020 г., 09:22:52 ч. Гринуич+2, Latchezar Filtchev написа:

[ovirt-users] Upload ISO to data domain - checksum mismatch on the brick

Hello Community, I'm currently migrating all my ISOs from the ISO domain to the DATA domain but it seems that the checksum (on brick level) mismatches.The problem is that I have managed to upload several ISOs (one of them 4.9GB) without issues. Restarting the ovirt-imageio-proxy.service and later

Hi Strahil, Unfortunately virtio drives cannot be used. Guest OS is CentOS 5.2, kernel 2.6.18-92.1.17.el5.centos.plusPAE The network connectivity of the VM is very short (please see below). Till I connect the VM (via spice) network connectivity is already gone. tcpdump –I eth0 –v tcpdump: liste

This seems quite odd. What happens when you set custom compatibility mode to 4.2 ? I think it was in Edit -> system -> Advanced options -> Custom compatibility mode -> 4.2 Best Regards, Strahil NikolovOn Jan 12, 2020 13:24, Latchezar Filtchev wrote: > > Hi Strahil, > >   > > Unfortunately

[ovirt-users] Re: Unstable VM network connectivity after upgrade 4.2.8 to 4.3.7

Yes! It is. After upgrade 4.2 to 4.3 datacenter and cluster compatibility mode was 4.2 when I discovered the issue. Then I set Cluster mode to 4.3 – no luck. It is not so easy to return it to 4.2. Thank you! Best, Latcho From: Strahil Sent: Sunday, January 12, 2020 2:20 PM To: Latchezar Filt

[ovirt-users] Re: Unstable VM network connectivity after upgrade 4.2.8 to 4.3.7

I guess I didn't clarify myself. I asked if you can shutdown the VM and then set only this VM's 'Custom compatibility mode' to 4.2 and power up to test. Yet, if the cluster was at 4.2 when you imported , then I am afraid that the 'Custom Compatibility mode' won't make a difference. I'd recomme

Hi, Can you please provide more details? 1) Origin domain type. 2) Destination domain type & size. 3) Was VM up or not? Live Migration? 4) Engine logs if you have. Thanks! Pavel On Thu, Jan 9, 2020 at 12:29 PM Demeter Tibor wrote: > Dear Users, > > I have exactly same problem. > When I trying

[ovirt-users] Re: Low disk space on Storage

Hi Demeter, my guess is that you have a linux system running there.Usually even in a SAN-based environement , we keep our Bare-Metal Hosts with LUNs no bigger than 2 TB. Picking 16TB as a single disk is a poor choice and I would recommend you to do a "pvmove" on the OS to smaller disks . Best R

[ovirt-users] Re: Unstable VM network connectivity after upgrade 4.2.8 to 4.3.7

You were OK. I misunderstood. Checked and changed VM compatibility mode. It is the same. Bug – I will continue to troubleshoot. At least to convince myself that this is not caused by hardware used. Then I will file a bug. Thank you! Best, Latcho From: Strahil Sent: Sunday, January 12, 2020 5:

Dear Strahil, Last strange discovery. Newly installed VM – same OS, same NIC’s – connected to the same VLAN’s. Both machines are running on the same virtualization host. Newly installed VM – no network issues at all. It works flawlessly. It is really very strange. Best, Latcho From: Strahil

[ovirt-users] Re: Unstable VM network connectivity after upgrade 4.2.8 to 4.3.7

Maybe it's related to the CentOS 5.2 e1000 kernel module . Can you install another CentOS 5.2 and verify that the issue exists? Any chance to upgrade the VM to 5.11 or just update the kernel so it is at least 2.6.25 , so you can try the virtio NIC ? Best Regards, Strahil NikolovOn Jan 12, 202

[ovirt-users] Re: Unstable VM network connectivity after upgrade 4.2.8 to 4.3.7

Can you check for any differences betwewn the newly created VM and the old one. Set an alias as follows: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Then: virsh dumpxml oldVM virsh dumpxml newVM Maybe somethhing can give a clue what is going on. Be
