    MasterIn this study, we propose a machine learning model that predicts failures by analyzing logs before failures occur in virtual machines (VMs) used in network function virtualization (NFV) environments. The proposed model utilizes a convolutional neural network (CNN) and includes pre-processing and pre-failure tagging techniques. We collected log data from VMs built on OpenStack to validate the proposed model. We classified failures based on early fault messages and built a CNN model to predict VM failures with fault messages. The experimental results showed that the proposed model can predict failures within a 5-min period with an F1-score of 0.67. The proposed model could be used for VM proactive live migration to avoid service degradation and interruptions caused by failures.λ³Έ μ—°κ΅¬μ—μ„œλŠ” NFV ν™˜κ²½μ—μ„œ 가상 λ¨Έμ‹  (VM)에 λ°œμƒν•˜λŠ” κ³ μž₯을 μ˜ˆμΈ‘ν•˜λŠ” λͺ¨λΈμ„ μ œμ•ˆν•˜κ³  μ‹€ν—˜μ„ 톡해 κ²€μ¦ν–ˆλ‹€. μ œμ•ˆν•œ λͺ¨λΈμ€ VNFκ°€ μ„€μΉ˜λœ 가상 λ¨Έμ‹ μ—μ„œ μΆ”μΆœν•œ 둜그λ₯Ό λΆ„μ„ν•˜μ—¬ 일정 μ‹œκ°„μ΄ κ²½κ³Όν•œ 뒀에 κ³ μž₯이 일어날지 아닐지λ₯Ό νŒλ‹¨ν•œλ‹€. μš°λ¦¬λŠ” 기쑴의 sentence classification λ¬Έμ œμ—μ„œ μ‚¬μš©λ˜λŠ” ν•©μ„±κ³± 신경망 κΈ°μˆ μ„ μ μš©ν•˜μ˜€μœΌλ©°, 가상 λ¨Έμ‹ μ˜ 둜그 뢄석에 μ ν•©ν•œ 데이터 μ „μ²˜λ¦¬, log word embedding, pre-failure tagging λ“±μ˜ 기법을 ν•¨κ»˜ μ‚¬μš©ν•˜μ—¬ 더 높은 탐지 μ„±λŠ₯을 갖도둝 ν•˜μ˜€λ‹€. μš°λ¦¬λŠ” OpenStackμ—μ„œ μƒμ„±ν•œ λ°μ΄ν„°λ‘œ μ œμ•ˆν•œ λͺ¨λΈμ„ κ²€μ¦ν–ˆμœΌλ©°, κ·Έ κ²°κ³Ό, μ œμ•ˆν•˜λŠ” 방법이 5λΆ„ μ΄ν›„μ˜ κ³ μž₯을 F1-score 0.67둜 μ˜ˆμΈ‘ν•  수 μžˆλŠ” 것을 ν™•μΈν•˜μ˜€λ‹€. ν•˜μ§€λ§Œ μ‹€μ œλ‘œ λ°œμƒμ‹œν‚¬ 수 μžˆλŠ” κ³ μž₯ 데이터가 λ§Žμ§€ μ•ŠκΈ° λ•Œλ¬Έμ— ν–₯ν›„ μ—°κ΅¬λ‘œμ„œ 더 λ§Žμ€ 데이터λ₯Ό μƒμ„±ν•˜μ—¬ 연ꡬ에 ν™œμš©ν•  μ˜ˆμ •μ΄λ‹€
