Slow command output in KVM Debian Guests


(Shyamin Ayesh) #1

Hi,

I’m running ON front end ( isolated VM ) + single KVM node backed by 2 SATA disk in RAID1 ( HP P400 ). I did some disk benchmarks and got some reasonable results as per my knowledge.

But there is small issue when issuing commands. Some command output takes few seconds to execute and output.

I attached a GIF image, is anyone can help me to resolve this delay ?

PS : I just found out that this only happening on Debian guest KVM’s
