Hi everybody,
I have a server with 760GB of RAM. I have only domain 0 running there
with 16GB of ram assigned to it.
Here is a configuration for my user domain:
name = "node01"
kernel = "/boot/vmlinuz-5.15.0-82-generic"
root = "/dev/xvda"
memory = 614400
maxmem = 614400
vcpus = 32
maxvcpus = 32
disk = ['file:/vserver/images/node01.img,xvda,w']
vif = ['bridge=virbr0,mac=00:16:3e:01:01:02']
iommu = "soft"
swiotlb = "force"
pci_permissive = 1
pci =
['0000:3e:00.0','0000:3f:00.0','0000:40:00.0','0000:41:00.0','0000:b1:00.0','0000:b2:00.0']
nics = 1
dhcp = "off"
ip = "192.168.122.15"
netmask = "255.255.255.0"
gateway = "192.168.122.1"
hostname = "node01"
extra="3"
When I try to start the domain, it spins in a crash loop with following
error messages:

Any suggestion what I am doing wrong? There should be plenty of RAM to
start 600GB domain. I can start user domain with 500GB no problem.
Thank you in advance for your help and suggestions.
