ClickCease QEMUCare - Automated QEMU/KVM Vulnerability Patching

Need to Buy Some
Time to Migrate?

QEMUCare enables you to automatically deploy patches with:

  • Zero
  • Zero Downtime
  • Zero Maintenance Windows
  • Zero Headaches

Conventionally, patching the QEMU/KVM hypervisors that support OpenStack, ProxMox or OpenNebula would involve a reboot or migration of your virtual machine to another running hypervisor.
But delaying patches to coordinate a migration or reboot is leaving your architecture vulnerable, and your end-users may be noticing the service disruption involved.

TuxCare’s QEMUCare live patching solution enables cloud providers, virtual private server (VPS) hosts, or any other organization with QEMU-based virtualization systems to automate their infrastructure patching without needing to orchestrate an inconvenient reboot or disrupt virtual tenants’ systems.
